Answer 1

Hello, take a look below:

Let's look at this problem piece by piece.

The cost of parts is $149, which is a one time price that must be paid, regardless of the hours spend working on the car. Thus, 149 is a constant in the expression, since their is no variable attached to it. That amount is going to be added onto the cost of labor per hour.

For every hour h, an additional $35 must be paid. This should be represented by 35h, meaning 35 times the amount of hours h.

Let's use the letter C to represent cost of the whole repair.

C = 35h + 149
