Question

Ryan had 240 cds. Sharon had 9/2 of the number of cds Ryan had. Sharon gave 75 cds to her friends. Find the percent decrease in the number of cds Sharon had. Round your answer to 2 decimal places.

Answer 1

6.94% First, determine how many CDs that Sharon started with by multiplying 240 by 9/2. So 240 * 9/2 = 1080 Now what percent is 75 of 1080? Simple division will give you that. 75 / 1080 = 0.069444444 = 6.9444444% So Sharon had a 6.94% decrease in the number of CDs she had.
