Answer :
Final answer:
The donation can be used to feed 0 families.
Explanation:
To find out how many families can be fed by the donation, we need to divide the total amount of food donated by the amount of food each family will receive. First, we add the weights of the donations: 103 lb + 91 lb = 194 lb. Then, we divide this total by the weight of food each family will receive: 194 lb ÷ 310 lb = 0.625. Since we can't have a fraction of a family, we would round down to the nearest whole number. Therefore, the donation can be used to feed 0 families.
