Boston Fall is a new self-service salad restaurant. Dan went to the restaurant and asked for half a cucumber, one large potato, two carrots, three onions, three tomatoes, and one corncob.
The cost of one cucumber is a dollar; one large potato is 1⁄2 a dollar; one carrot is 3⁄4 of a dollar; one onion is 1⁄8 of a dollar; one tomato is 2 1⁄3 dollars; and one corncob is 3⁄8 of a dollar.
Dan came back with two friends: Michael asked for the same ingredients in his salad but with half the amount of each vegetable, and Brian asked for the same ingredients but with triple the amount of each vegetable. Dan offered to pay for everything.
What is the difference between the price Dan paid for the three salads and the price Dan would have paid for his salad only?
