Sue initially has 5 hours of pop music and 4 hours of classical music in her collection. Every month onwards, the hours of pop music in her collection is 25% 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(1.25)x + 5
f(x) = 5(1.25)x + 4
f(x) = 4(0.25)x + 5
f(x) = 5(0.25)x + 4
