Hello there, and thank you for posting your question here on brainly.
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!! ☺♥
