Math Problem of the Week - Lower Elementary - Nov. 28, 2021 to Dec. 4, 2021

Lower Elementary: 

Question: A sheepdog has a litter of 7 puppies and 1 adopted piglet. Each puppy eats 2 cups of food per day. The piglet eats twice as much as a puppy. How many cups of food do the baby animals need each day in total?

Answer: 18 Cups

Solution:  Since each of the 7 puppies eats 2 cups of food each day, all of the puppies eat 2, 4, 6, 8, 10, 12, 14 cups of food in a day. The piglet eats twice as much as a puppy, and twice as much as 2 cups is 4 cups. So, the baby animals eat 14 + 4 = 18 cups of food in total.
