Answer:
f(g(x)) =

Step-by-step explanation:
f(x) =

g(x) = 8x - 13
f(g(x) =

121/2 = 720/p
720*2= 121p
1440=121p
divide by 121
=12%
First - 8
second - 4
third - 12
fourth - 9
Percentage increase = (increase) x 100 / original
Percentage increase = (5,800,000 - 5,000,000) x 100 / (5,000,000)
Percentage increase = 16%
