Answer 1

Answer: c) 109

Explanation:

Given : 302 car stereos were recently sold in a car audio store.

Number of stereos had a CD player = 149

Number of stereos had a cassette player =116

Number of stereos had both a CD and a cassette player =40

Then, the number of stereos had a CD player only = Number of stereos had a CD player - Number of stereos had both a CD and a cassette player

= 149- 40 = 109

∴ The number of stereos had a CD player only = 109

Hence, the correct answer is c) 109 .
