!!! Your parents decide that they will help you out for the first two months after graduating from college by helping you buy groceries for your meals, but they won’t cover the cost of you going out to eat at restaurants or fast food. For the first month you submit your receipts, 13 receipts for fast food and four receipts for Krogers, and they totaled $487. The second month you submit receipts for six fast food meals and two purchases from Krogers, and totaled $232. The receipts do not list the per-item price. What were the average costs of one fast food meal and of one trip to Krogers? Show your work and explain your answer.
