Answer 2

Answer:
5x + b = 22

The variable b stands for the flat fee of labor and the 5x stands for the quarts of oil and the price.

First, we would plug in numbers for the variable x.

Let’s say, we plugged in 3, 5(3) = 15

So, 5(3) + b = 22

That equation is solvable and would equal,
B= $7 flat fee
X= $3 per quart of oil
