Wendy initially has 6 hours of pop music and 3 hours of classical music in her collection. Every month onwards, the hours of pop music in her collection is 9% 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?

f(x) = 6(1.09)x + 3

f(x) = 3(1.09)x + 6

f(x) = 6(0.09)x + 3

f(x) = 3(0.09)x+ 6

In the problem, it says the 6 doesn't change so you can throw out option A and C. I had a similar problem in class the answer maybe f(x)=3(1.09)x+6 because that is what my teacher said in a similar problem. I can't really explain it because I didn't get it but I hope it helps you.

Answer:

It's A  f(x) = 6(1.09)x + 3
