Hello there, and thank you for posting your question here on

So 10% of Ahyoka's CD's are hip hop, and 70% are pop.

Let's put it into equation.

(Let p = pop and c = cd's)

x = p * c

Or 

x = 10% * 250

Turn 10% into a decimal, and then multiply.

10% = 0.1

Now we have x = 0.1 * 250.

Do the multiplication.

0.1 * 250 = 25

25 CD's are hip hop.

Hope this helped!! ☺♥
