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 29 gallons. 9 gallon tank size is 20.35 total cost. 16 gallon tank size is 33.65 total cost. 20 gallon tank size is 41.25 total cost. Answers; A. f(x) = 1.70x+3.75 cost for truck=$53.05 B. f(x) =1.90x+3.25 cost for truck=$58.35 C. f(x) =0.53x+1.71 cost for truck=$17.08 D. f(x) =2.00x +3.50 Cost of truck = $61.50
