For this case we have the following equation:
Resolving we have the following steps:
----> Given equation
----> Multiplication Property of equality: Multiply by 3 both sides of the equation
----> Distributive property: You solve the operation of the factor with the elements of parentheses
----> Property addition of equality: Because it adds 1 to both sides of equality.
----> Substraction Property of equality: Subtract 6x on both sides of equality
----> Division Property of equality: You divide both sides of the equality between -4.

Answer:
See explanation
Step-by-step explanation:
A. Gasoline fill-up fee = $4.50
Cost per hour = $40
Average cost = C
Number of hours the scootcar is rented = h
Cost per h hours = $40h
Total cost = $40h + $4.50
Hence,
C = 40h+4.5
B. To plot the graph of the function, find h- and C- intercepts.
When h = 0, then C = 4.5, and we have point (0,4.5)
When C = 0, then 0 = 40h + 4.5, h = -45/400 = -0.1125, and we have point (-0.1125,0)
Plot these two points and connect them with a straight line.
Graph is attached, but you should take only that part of the graph that corresponds to points with h > 0, because the number of hours cannot be negative
