Stream of consciousness rationale: At each feeding Billy serves 4 horses x 4 pounds of oats / horse = 16 pounds / feeding. Each day Billy uses 16 pounds of oats / feeding x 2 feedings / day = 32 pounds of oats / day. Triple that amount to find the amount of oats needed to feed the four horses for three days: 32 pounds of oats / day x 3 days = 96 pounds.
The question and answer pair are described below.
Q: Billy has four horses. Each one eats 4 pounds of oats, twice a day. How many pounds of oats does he need to feed his horses for 3 days?
A: 96
