Gas Mileage Daniel is trying to decide whether to buy a car or a truck. The truck he is considering will cost him $150 a month in loan payments, and it gets 20 miles per gallon in gas mileage. The car will cost $180 a month in loan payments, but it gets 35 miles per gallon in gas mileage. Daniel estimates that he will pay $4.00 per gallon for gas. This means that the monthly cost to drive the truck x miles will be y= x+ 150. The total monthly cost to drive 1.00 the car x miles will be y x+ 180. The following 4.00 20 %3D figure shows the graph of each equation. 400 350 300 250 Ear 200 Truck 150 100 50 100 200 300 400 500 600 700 800 900 Miles driven in a month a. At how many miles do the car and the truck cost the same to operate? b. If Daniel drives móre than 600 miles in a month, which will be cheaper? c. If Daniel drives fewer than 100 miles in a month, which will be cheaper? Cost ($)
