NJSLA Solving Multi-Step Math Problems 4 — Questions and Answers
Question 1: A cell phone plan charges $25 per month plus $0.10 per text message. In January, Marcus sent 340 texts, and in February he sent 210 texts. How much did he pay in total for both months?
- $105 (Correct answer)
- $95
- $110
- $100
Correct answer: $105
January: $25 + 340 × $0.10 = $25 + $34 = $59; February: $25 + 210 × $0.10 = $25 + $21 = $46; total = $59 + $46 = $105.
Question 2: A class of 28 students took a field trip. The cost per bus is $120 and each bus holds a maximum of 14 students. The school also charges each student $8 for admission. What is the total cost of the field trip?
- $464 (Correct answer)
- $480
- $488
- $456
Correct answer: $464
Buses needed = ⌈28 ÷ 14⌉ = 2 buses; bus cost = 2 × $120 = $240; admission = 28 × $8 = $224; total = $240 + $224 = $464.
Question 3: An athlete runs at 8 mph for 30 minutes, walks at 3 mph for 20 minutes, then sprints at 12 mph for 10 minutes. What is the total distance covered?
- 7 miles (Correct answer)
- 6 miles
- 8 miles
- 5.5 miles
Correct answer: 7 miles
Running: 8 × (30/60) = 4 miles; walking: 3 × (20/60) = 1 mile; sprinting: 12 × (10/60) = 2 miles; total = 4 + 1 + 2 = 7 miles.
Question 4: A store manager wants to display 252 cans equally on shelves. Each shelf holds 18 cans and each shelf unit has 4 shelves. How many shelf units does the manager need?
- 3.5 units
- 4 units (Correct answer)
- 3 units
- 5 units
Correct answer: 4 units
Total shelves needed = 252 ÷ 18 = 14 shelves; shelf units needed = 14 ÷ 4 = 3.5, so 4 units are required (must round up).
Question 5: The temperature dropped from 14°F to −8°F overnight, then rose 5°F by noon. What was the temperature at noon?
- −3°F (Correct answer)
- 3°F
- −11°F
- 11°F
Correct answer: −3°F
Starting at 14°F, dropping to −8°F is a change of −22°F; then rising 5°F gives −8 + 5 = −3°F.
Question 6: Kevin saves $55 per week. After 8 weeks he spends $140 on shoes and $95 on a jacket. How much money does Kevin have left?
- $205 (Correct answer)
- $195
- $185
- $215
Correct answer: $205
Total saved = 8 × $55 = $440; total spent = $140 + $95 = $235; remaining = $440 − $235 = $205.
Question 7: A pizza is cut into 12 equal slices. The Chen family eats ⅓ of the pizza at lunch and ¼ of the pizza at dinner. How many slices are left?
- 5 slices (Correct answer)
- 4 slices
- 6 slices
- 3 slices
Correct answer: 5 slices
Eaten at lunch = ⅓ × 12 = 4 slices; eaten at dinner = ¼ × 12 = 3 slices; remaining = 12 − 4 − 3 = 5 slices.
