g(- 4) = 3(- 4) - 5 = - 12 - 5 = - 17, then

f(- 17) = 4(- 17) + 7 = - 68 + 7 = - 61 → B

Answer:

x=1

Step-by-step explanation:

To solve for x, we need to get x alone on one side of the equation.

Add one to each side of the equation. Subtract 8x from each side of the equation. Divide both sides by -7. You should get 1 as the answer.

$-1+x=8x-8\\x=8x-7\\-7x=-7\\x=1$

(Original cost)(6%)=5.25
(Original cost)(0.06)=5.25
(original cost)=5.25/0.06=87.5
