Question: 588
17. Fifty percent of the 20 students in Mrs. Schweizer's third-grade class are boys. If 90 percent of these boys ride the bus to school, which of the following is the number of boys in Mrs. Schweizer's class who ride the bus to school?
- A. 9
- B. 10
- C. 12
- D. 16
Correct Answer: A
Explanation:
Take this question in bite-sized pieces. 50% of the 20 students are boys. This means that half of the students are boys, so 
(20) = 
= 10. Since there are 10 boys, 90% of the 10 boys take the bus to school, which is equal to 
(10) = 
= 9. The correct answer is (A).
