Question 1: A table shows prices per pound: apples $1.50, oranges $2.00, bananas $0.75. If Sarah buys 4 lbs of apples, 2 lbs of oranges, and 3 lbs of bananas, what is her total cost?
- $12.25 (Correct answer)
- $11.50
- $13.00
- $10.75
Correct answer: $12.25
(4×$1.50)+(2×$2.00)+(3×$0.75) = $6.00+$4.00+$2.25 = $12.25.
Question 2: According to a graph, a car travels 150 miles in 2.5 hours. What is the car's average speed?
- 60 mph (Correct answer)
- 65 mph
- 55 mph
- 70 mph
Correct answer: 60 mph
Average speed = distance ÷ time = 150 ÷ 2.5 = 60 mph.
Question 3: A frequency table shows library visits: 0 visits=5 students, 1 visit=8 students, 2 visits=12 students, 3 visits=5 students. How many students were surveyed in total?

Adding all groups: 5+8+12+5 = 30 total students surveyed.
