A6 ounce drink costs 2.16 and a 10 ounce drink costs 3.25 which drink is the better buy justify your answer

The ten ounce drink is a better deal. Since you are getting 10 ounces of a drink you spend only 32 cents on each ounce whereas with the 6 ounces you end up spending 36 cents per ounce. You might be spending more money on the ten ounces but when you break down the cost of the drink per ounce you figure out that it is the best deal possible
