i have math homework college quantitative reasoning math 117 need help with my homework the number of cds sold in 2010 was 114 million down from147 million the previous year find the absolute and relative percent decrease

Answer 1

According to the problem, the number of CDs sold in 2009 was 147 million, and in 2010 it was 114 million.

To find the absolute decrease, we just have to subtract

`147-114=33`

Hence, the absolute decrease was 33 million CDs.

To find the relative decrease, we just have to divide 33 by 147

`(33)/(147)=0.2245`

Then, we multiply by 100 to express it as a percentage.

`0.2245*10=22.45`

Hence, the relative decrease was 22.45%.
