Question

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

Answer 1

a or d?

Answer 2

your guess

Answer 3

eh D.. that is prob wrong

Answer 4

The answer is A
If she's listening to 6 hours of pop, and that's increasing by 9%, you're gonna multiply 6 hours by 1.09, to show that it's 109% of what she used to listen to. Then you add 3 on, because it's a constant. Make sense?

Answer 5

Yeah that makes sense
