Answer 3

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.


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.


B.


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.


C.


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.


D.


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.
