The cost to fill a car's tank with gas and get a car wash is a linear function of the capacity
of the tank. The costs of a fill-up and a car wash for three different customers are shown
in the table. Write an equation for the function in slope-intercept form. Then, find the
cost of a fill-up and a car wash for a customer with a truck whose tank size is 28 gallons.
