Question. Farmer Red has three milk cows: Bess, Brownie, and Daisy. Bess, the smallest cow, gives him two pails of milk every day. Brownie, the largest cow, produces three times that amount. Then Daisy makes one pail more than Bess. How many pails of milk does Farmer Red get from them each week?
Answer. 77
What step-by-step reasoning justifies that answer?
Reasoning: Bess produces 2 pails every day. Brownie produces 3 times as much * 2 = 6 pails every day. Daisy produces 2 + 1 more pail than Bess = 3 pails every day. Bess, Brownie, and Daisy together produce 2 + 6 + 3 = 11 pails every day. A week is 7 days, so Farmer Red gets 11 * 7 = 77 pails each week.
