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

you originally have 6 hours of pop music
you get a 9% increase of 6
what is 9% of 6?
since it was increase by 9%
that is the same as 109% of the original
which is the same as 6(1.09)
since for each month you increase the amount of pop, you need a variable x in there, which would stand for the number of months gone by

so you have 6(1.09)x

you have 3 hours of classical music, add that to the amount you have

so you end up getting which function?

Answer 2

yah :D

Answer 3

im sorry i was eating

Answer 4

so is it C?

Answer 5

no

Answer 6

6(1.09) for the 9% increase
6(1.09)x for the variable for the number of months
6(1.09)x + 3 to add on classical
f(x)=6(1.09)x + 3
