    Sharon solved this problem. The zoo needs 1436 pounds of hay each week to feed the animals. Hay costs $2.00 per pound. About how much does the zoo spend on hay each week? Sharon said the zoo would spend $718 on hay each week. Is Sharon's answer reasonable? A. No, because 1500 • 2 = 3000, and the zoo needs 1436 pounds of hay each week, so the answer will be a bit more than this estimate. B. Yes, because 1500 ÷ 2 = 750, and the zoo needs 1436 pounds of hay each week, so the answer will be a bit more than this estimate. C. No, because 1400 • 2 = 2800, and the zoo needs 1436 pounds of hay each week, so the answer will be a bit more than this estimate. D. Yes, because 1400 ÷ 2 = 700, and the zoo needs 1436 pounds of hay each week, so the answer will be a bit more than this estimate.
