Question: 328
6. Bob’s i-Pod contains 800 songs. If 240 songs are either jazz or rap songs, what percent of his collection is jazz or rap?
- A. 15%
- B. 20%
- C. 25%
- D. 30%
Correct Answer: D
Explanation:
D is correct. To calculate the percent, divide the number of jazz and rap songs by the total number of songs. 240 ÷ 800 = 0.30. To change that to a percent, move the decimal point two places to the right and add the percent sign to get the correct answer of 30%.
