Fruits and vegetables are sold by the pound. Add up your prices per pound for the fruits and vegetables and find the average cost per pound. (Example: If bananas are .79 per pound and apples are .59 per pound, the average is calculated like this: (.79 + .59)/2 = 1.38/2 = .69 per pound on average for the two fruits.)Locate the weight of your prepackaged food items. (For example, on a box of Frosted Flakes it says 15 oz.)
