Question

Meg initially has 3 hours of pop music and 2 hours of classical music in her collection. Every month onwards, the hours of pop music in her collection is 5% more than what she had the previous month. Her classical music does not change. Which function shows the total hours of music she will have in her collection after x months?

A) f(x) = 2(0.05)x + 3

B) f(x) = 3(0.05)x + 2

C) f(x) = 2(1.05)x + 3

D) f(x) = 3(1.05)x + 2

Answer 1

I believe the answer is B. Initially she had 3 hours of pop music, so you would multiply that by how much it increases, which is 5% and you would only add 2 because there should only be 2 hours of classical music.
