Stretch Problem
Real-world application: You are planning a class supply budget of $75
for 28 students. Each student needs 2 pencils ($0.25 each), 1 notebook
($1.50), and 1 folder ($0.75). Will $75 cover everyone? If not, how
much more is needed, and what is one change you could make to stay
within budget? Show all calculations and explain your reasoning.
Answer Key
- 234 + 178 = 412 forward; 412 − 156 = 256 miles from start.
- Week: 1,248 × 5 = 6,240. Month: 6,240 × 4 = 24,960 widgets.
-
Shirts $73.50 + shoes $134.50 = $208.00; $500 − $208 = $292 left.
-
1×72, 2×36, 3×24, 4×18, 6×12, 8×9 (6 pairs). Stop at √72 ≈ 8.5 since
pairs repeat after that.
- 32 × 28 = 896 seats; 896 − 647 = 249 empty.
-
312 ÷ 3 = 104 (middle); numbers are 103, 104, 105. The middle term
is the mean of evenly spaced numbers.
- LCM(6, 8) = 24; multiples 24, 48, 72, 96, 120 → answer 120.
-
71 × 53 = 3,763 (largest). Put the largest digits in the tens
places.
- 1+2+…+12 = (12 × 13) ÷ 2 = 78 chimes.
-
Outer 30 × 24 = 720 sq ft; garden 24 × 18 = 432; path = 720 − 432 =
288 sq ft.
-
Stretch: pencils 28×2×$0.25 = $14; notebooks 28×$1.50 = $42; folders
28×$0.75 = $21; total $77 → $2 over. Answers vary on the cut (e.g.,
drop folders or buy 1 pencil each).
