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 22 gallons.

Of(x) = 2 20x + 3.50; Cost for truck = $51.90
O fx) – 2. 30x + 3.25 Cost for truck = $53.85
Of(x) = 2.00x +3.25, Cost for truck = $47.25
None of the other answers are correct
Of(x) - 0.45x+1.59: Cost for truck = $11.49
