Phase 1: Mission Briefing
Welcome, future Mall Mogul! Learn about your mission.
👜 Your Mission
Congratulations! You have been chosen to become the Chief Retail Officer of a brand-new shopping mall. Your job is to open stores, set prices, calculate discounts, determine sales tax, and manage your entire retail empire. Every decision requires percents, decimals, and rates.
Your starting investment is $100,000. You will use percent calculations to set markups, offer discounts, compute tax, and analyze profit margins. Make smart mathematical decisions to build the most profitable mall!

Percent & Decimal Vocabulary Review
Before we start building your empire, review the key math
vocabulary you will use throughout this project.
Percent
A ratio out of 100. Example: 25% means 25 out of 100, or
0.25 as a decimal.
Markup
The amount added to cost price. A 40% markup on $50 = $50 +
0.40 × 50 = $70.
Discount
A percent taken off the price. 20% off $80 = $80 −
0.20 × 80 = $64.
Sales Tax
A percent added to a purchase. 7% tax on $64 = $64 +
0.07 × 64 = $68.48.
To convert a percent to a decimal, divide by 100 (or move the
decimal point 2 places left). 45% = 45 / 100 = 0.45. To find a
discount: multiply the price by the percent as a decimal, then
subtract from the original price.
📚 Support: Think of percent as "per
hundred." 45% means 45 per 100. To change to a decimal, move the
dot two spots to the left: 45% becomes 0.45. For 6%, think of it
as 06% which becomes 0.06.

Mall Budget Overview
Study the budget breakdown for your mall. You will use percents of
your $100,000 investment for each category.
| Category | Percent of Budget | Dollar Amount | Purpose |
|---|---|---|---|
| 🏷 Store Buildout | 40% | Constructing store spaces | |
| 📦 Inventory | 25% | Buying products to sell | |
| 📣 Marketing | 15% | Advertising & promotions | |
| 👥 Staff | 12% | Hiring employees | |
| 💰 Emergency Fund | 8% | Unexpected expenses |
🌟 Challenge: If the investor decides to
increase the budget to $150,000, what would each category's dollar
amount be? Calculate all five.
To find a percent of a number, convert the percent to a decimal
and multiply. 40% of $100,000 = 0.40 × 100,000 = $40,000.
Phase 2: Market Research
Research pricing, discounts, and tax to make smart decisions.

Enter a percent and a dollar amount to find the percent of that
number. Great for markups, discounts, and tax!

Setting Prices with Markups
As a store owner, you buy products at
wholesale cost and sell them at a
retail price by adding a markup.
Calculate the selling price for each item using the given markup
percent.
| Product | Wholesale Cost | Markup % | Markup Amount | Selling Price |
|---|---|---|---|---|
| 👕 Designer T-Shirt | $12.00 | 75% | ||
| 👟 Sneakers | $40.00 | 120% | ||
| 💻 Tablet Case | $8.00 | 150% | ||
| 🎨 Art Print | $5.50 | 200% |
Markup Amount = Wholesale Cost × Markup Percent (as
decimal). For the T-Shirt: $12.00 × 0.75 = $9.00 markup.
Selling Price = $12.00 + $9.00 = $21.00.
📚 Support: To find 75% of $12: First
change 75% to a decimal: 0.75. Then multiply: 0.75 × 12 = 9.
That is the markup amount ($9). Add it to the original cost: $12 +
$9 = $21 selling price.
5
Discount Sale Research
Your competitor mall is running sales! Research what customers
actually pay after these discounts.
| Item | Original Price | Discount % | Show Your Work | Sale Price |
|---|---|---|---|---|
| 👔 Jacket | $95.00 | 25% off | ||
| 👟 Boots | $120.00 | 40% off | ||
| 💼 Backpack | $65.00 | 15% off | ||
| 📱 Phone Case | $35.00 | 50% off |
🌟 Challenge: A store has a "double
discount" — first 20% off, then an additional 10% off the
already-reduced price. Is this the same as 30% off? Prove it using
a $100 item.

Sales Tax Calculations
In your state, the sales tax rate is 7%.
Calculate the total cost including tax for each purchase.
Remember: total = price + tax.
Sales Tax = Price × Tax Rate (as decimal). For $45 at 7%:
Tax = $45 × 0.07 = $3.15. Total = $45 + $3.15 = $48.15.
For the reverse: Total = Original × 1.07, so Original =
Total / 1.07.
📚 Support: To find 7% tax: multiply the
price by 0.07. Example: $45 × 0.07 = $3.15 (that is the
tax). Then add tax to the price: $45 + $3.15 = $48.15 (that is the
total you pay).
7
Food Court Tip Calculations
Your mall has a food court with sit-down restaurants. Customers
leave tips based on their bill total. Calculate the tip amount and
total for each scenario.
| Restaurant | Bill Amount | Tip % | Tip Amount | Total with Tip |
|---|---|---|---|---|
| 🍕 Pizza Palace | $24.00 | 15% | ||
| 🍣 Sushi Spot | $56.00 | 20% | ||
| 🍔 Burger Barn | $18.50 | 18% |

Comparing Unit Prices
A smart mogul always finds the best deal! Compare unit prices to
decide which supplier to order from.
📦 Supplier Comparison
You need to order phone cases for your tech store. Three suppliers offer different deals. Find the unit price (price per case) for each to determine the best deal.
Supplier A
24 cases for $168
Supplier B
36 cases for $234
Supplier C
50 cases for $300
📚 Support: To find the unit price, divide
the total cost by the number of items. For Supplier A: $168 / 24
cases = $7.00 per case. The lowest unit price is the best deal!
11
Decimal Operations — Inventory Tracking
Your stores need accurate decimal math for inventory and cash
register operations. Solve each problem.
Line up the decimal points when adding or subtracting. When
multiplying decimals, multiply as if whole numbers, then count
total decimal places. When dividing, move the decimal to make
the divisor whole.
Phase 4: Grand Opening Build
Launch your mall with real sales scenarios and profit analysis!
12
Grand Opening Sale Event
For your grand opening, you are running a
30% off everything sale! Calculate the sale
prices and total with 7% tax for each customer's purchase.
Discount + Tax Calculator
Enter values to calculate discount then tax...
| Customer | Items (Original) | After 30% Off | 7% Tax | Final Total |
|---|---|---|---|---|
| Customer A | $75.00 jacket | |||
| Customer B | $120.00 sneakers | |||
| Customer C | $45.00 + $30.00 | |||
| Customer D | $199.99 game system |
13
Daily Sales & Profit Analysis
After your grand opening day, analyze each store's performance.
Profit = Revenue − Cost of Goods.
Profit Margin = (Profit / Revenue) × 100.
| Store | Revenue | Cost of Goods | Profit | Profit Margin % |
|---|---|---|---|---|
| Store 1 | $3,200 | $1,800 | ||
| Store 2 | $5,600 | $3,500 | ||
| Store 3 | $2,100 | $900 | ||
| Store 4 | $4,400 | $2,600 |
Profit = Revenue − Cost. Profit Margin = (Profit /
Revenue) × 100. For Store 1: Profit = $3,200 −
$1,800 = $1,400. Margin = ($1,400 / $3,200) × 100 =
43.75%.
📚 Support: Profit margin tells you what
percent of your revenue is actual profit. To find it: (1) Subtract
cost from revenue to get profit. (2) Divide profit by revenue. (3)
Multiply by 100 to get the percent. Higher margin = more efficient
store!

Monthly Revenue Projection
Based on your grand opening results, project monthly performance.
Use the daily totals and multiply to estimate 30-day revenue.

Percent Increase & Decrease
Compare your mall's performance week over week. Calculate the
percent change using:
% Change = (New − Original) / Original × 100
| Metric | Week 1 | Week 2 | Change | % Change | Direction |
|---|---|---|---|---|---|
| Visitors | 2,400 | 3,000 | |||
| Revenue | $15,300 | $18,360 | |||
| Returns | $1,200 | $900 |
