Your parents decide that they will help you out the first two months you are at 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 are for fast food and four for Kroger, and
totaled $487. The second month you submit receipts for six fast food meals and two for
Kroger, and totaled $232. The receipts do not list the per-item price.
