Question 7

Daniel is trying to decide whether to buy a car or a truck. The truck he is considering will cost him   a month in loan payments, and it gets 15 miles per gallon in gas mileage. The car will cost   a month in loan payments, but it gets   miles per gallon in gas mileage. Daniel estimates that he will pay   per gallon for gas. This means that the monthly cost to drive the truck x miles will be   The total monthly cost to drive the car x miles will be   The following figure shows the graph of each equation.   At how many miles do the car and the truck cost the same to operate?
