Question

Which equation could be used to solve the problem? Sarah spent $160 on lunch in 10 weeks. If she spent the same amount every week, how much did she spend on lunch each week (w)? A. w = 160 ÷ 10 B. w = 160 – 10 C. w = 10 • 160 D. w = 10 ÷ 160

Answer 1

The correct answer would be A, because 160/10 is getting you your unit rate, or the amount Sarah spent every week.
