Explanation:

Givens

• Ahyoka has 250 CDs.
• 10% are country.
• 70% are pop.
• The rest are hip-hop.

According to the problem, 10% of all CDs are country and 70% are pop, that gives a total of 80%. That means 20% of all CDs are hip-hop, because is the remaining part.

Now, we have to find the 20% of 250. We know that 20% equals 0.20, then

`0.20(250)=50`

Therefore, 50 CDs are hip-hop.
