Question

Harrison has 70 CDs in his music collection.

If 30% of the CDs are country music and 50% are pop music, how many CDs are other types of music?
There are
CDs that are other types of music.

Answer 1

14

Explanation:

First, find the percentage of the other types of music.

Since 30 + 50 = 80, the other 20% will be other music.

To find 20% of 70, multiply 70 by 0.2:

70(0.2)

= 14

So, there are 14 CDs that are other types of music.
