First you do $60 divided by 4 which equals $15
Then you take 1% of 15 which is 0.15 and multiply thirty percent by that and subtract thirty percent from 100% and get 70% which is 10.5
$320 5 times 20 is 100 so you have to times 16 by 20 to get the total 100% of the video game system

Hello,
if f(x)=y=x+3
x=y+3==>y=x-3
f^(-1) (x)=x-3 is the inverse function of f(x).
I think it's C, because first you multiply all the sides which is 112 then multiply by 3 and the answer it's 336 if I'm correct.
