the other music is 30 percent, yes you add 40 and 30 and you get 70.
100 is the whole and you subtract 70 from 100 and get 30

Answer: 9 CDs are other types of music.

Yes , you can add 40% and 30% to get the percentage of CDs that are country music or pop music.

Step-by-step explanation:

Given : Harrison has 30 CDs in his music collection.

Percentage of CDs are country music = 40%

Percentage of CDs are pop music= 30%

We will add 40% and 30% to get the percentage of CDs that are country music or pop music.

Percentage of CDs that are country music or pop music = 40% +30% = 70%

Percentage of other types of CDs = 100%-Percentage of country music or pop music

=100%-70%=30%

Now, the number of other types of CDs = Percentage of other types of CDs  x Total CDs

=30% of 30 =[tex]\dfrac{30}{100}\times30=9[/tex]

Hence, 9 CDs are other types of music.
