Daniel is trying to decide whether to buy a car or a truck. The truck he is considering will cost him $250 a month in loan payments, and it gets 20 miles per gallon in gas mileage. The car will cost $340 a month in loan
payments, but it gets 35 miles per gallon in gas mileage. Daniel estimates that he will pay $4.20 per gallon for
4.20
gas. This means that the monthly cost to drive the truck z miles will be y = -1 + 250. The total monthly
20
4.20
cost to drive the care miles will be y = -x + 340. The following figure shows the graph of each equation:

Multiply 1/9 by 9r and 3 = r + 1/3
then distribute the - sign = -r -4
and solve the problem r + 1/3 - r - 4 = 1/3-4 = -11/3
