HELP PLEASE WILL FAN AND MAKE BEST ANSWER!!

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?
A. f(x) = 4(1.25)x + 5
B. f(x) = 5(1.25)x + 4
C. f(x) = 4(0.25)x + 5
D. f(x) = 5(0.25)x + 4

Answer 1

C is Incorrect the correct answer is B.

The question states that the hours of pop music in her collection is 25% more than what it was the last month so it is increasing.

The correct answer is f(x) = 5(1.25)^x + 4

This is because in the question it states that the hours of classical music (4) does not change meaning that 4 is the constant and 5 is the initial value that changes over time (P).

Hope this helps.
