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.

O f(x) = 1.90x+ 3.75: Cost for truck = $56.95
Of(x) = 0.48x + 1.67: Cost for truck = $15.11
O f(x) = 2.20x + 3.00: Cost for truck = $64.60
