Acme super store is having a contest to give away shopping sprees to lucky families. if a family wins a shopping spree each person in the family can take any items in the store that he or she can carry out, however each person can only take one of each type of item. for example, one family member can take one television, one watch and one toaster, while another family member can take one television, one camera and one pair of shoes. each item has a price (in dollars) and a weight (in pounds) and each person in the family has a limit in the total weight they can carry. two people cannot work together to carry an item. your job is to the families select items for each person to carry to maximize the total price of all items the family takes. write an algorithm to determine the maximum total price of items for each family and the items that each family member should select.
