Which information is necessary to solve this problem? A computer company invited 3 students from each of the 50 states to compete in a contest.

3 students from each state = 3 * 50 = 150 there is extra info not needed in this problem...it is asking how many students were invited....that would be 150 (3 from each state).....it is not asking how many made it to the finals
texaschic101

texaschic101

just round your numbers... 7457 rounded = 7500 3908 rounded = 3900 so its : 7500 - 3900

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.
