CBEST Math: Computation and Problem-Solving 2 — Questions and Answers
Question 1: A store sells a jacket for $85. During a sale, the price is reduced by 20%. What is the sale price?
- $17.00
- $65.00
- $68.00 (Correct answer)
- $72.00
Correct answer: $68.00
20% of $85 is $17, so the sale price is $85 − $17 = $68.
Question 2: If 5x − 3 = 22, what is the value of x?
- 3
- 4
- 5 (Correct answer)
- 6
Correct answer: 5
Add 3 to both sides to get 5x = 25, then divide by 5 to get x = 5.
Question 3: A car travels 240 miles in 4 hours. At the same speed, how long will it take to travel 300 miles?
- 4.5 hours
- 5 hours (Correct answer)
- 5.5 hours
- 6 hours
Correct answer: 5 hours
The speed is 60 mph, so 300 ÷ 60 = 5 hours.
Question 4: What is the value of 3² + 4²?
- 14
- 25 (Correct answer)
- 49
- 7
Correct answer: 25
3² = 9 and 4² = 16, and 9 + 16 = 25.
Question 5: A recipe calls for 2¼ cups of flour. If you want to make 1½ times the recipe, how many cups of flour do you need?
- 3 cups
- 3⅜ cups (Correct answer)
- 3½ cups
- 3¾ cups
Correct answer: 3⅜ cups
2¼ × 1½ = 9/4 × 3/2 = 27/8 = 3⅜ cups.
Question 6: Which of the following is closest to √50?
- 6
- 7 (Correct answer)
- 8
- 9
Correct answer: 7
Since 7² = 49 and 8² = 64, √50 is closest to 7.
Question 7: A worker earns $12.50 per hour and works 38 hours in a week. What are her total weekly earnings?
- $450.00
- $462.50
