The answer would be 5,400 ( 3000 times 0.15 would be 450 then, 450 times 12 is 5,400.)
F(x)=2x+8
G(x)=x-4
Plug g(x) into f(x)
F(g(x))=2(x-4)+8
Distribute
F(g(x))=2x-8+8
Simplify
F(g(x))=2x
Answer:
$24, $30, $36
Step-by-step explanation:
First we need to find the unit rate.
1. 18÷3 = 6
So that means one taco costs $6.
6*4 = 24
6*5 = 30
6*6 = 36
