er looking at the DRI tables you are concerned that you may not be able to afford the food that will provide
enough protein for your diet. So, you decide to compare the price per gram of protein for the foods you commonly eat. The following four items were priced at Wal-Mart in 2014.
hint: find how many grams of protein are in whole package item. Then find unit rate. For example, if a tin of sardines has 2 servings and each serving has 5 grams of protein and I ate the whole tin I would have eaten 10 grams of protein. If the tin costs $2, each gram of protein cost me 20 cents.
