Sally initially has 4 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 8% 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) = 4(1.08)x + 3
f(x) = 3(1.08)x + 4
f(x) = 4(0.08)x + 3
f(x) = 3(0.08)x + 4

I don't really have an explanation, Dx

rhondasommer · Answer

to get 8 percent of her pop music you need to multiply 4(amount of hours of pop music she had already)by 0.08 because that is 8/100...then you add 3(amount of hours of classical music she had already) to get how many hours she has left.
