Answer:
$2.47
Step-by-step explanation:
The cabinetmaker would have paid $13.31 for everything.
(f o g)(-3) = (f(g(-3))
Because g is on the inside, we carry out g first.
g(x) = x^2 - 3
Substitute -3 in for x.
g(-3) = (-3)^2 - 3 = 9 - 3 = 6
g(-3) = 6
Next, carry out f on the result of g(-3)
f(6) = 2(6) - 1
= 12 - 1
= 11
So the answer is 11.

1. Make an equation.
Moving company #1: y = 17x + 840
Moving company #2: y = 22x + 760
2. Put the equations together and solve
17x + 840 = 22x + 760
-17x -17x
840 = 5x + 760
-760 -760
80 = 5x
5 5
16 = x
When a job is 16 hours they both charge the same thing.
