Question

Marcus completed 187 jumping jacks in 3 days. He completed 60 jumping jacks on each of the first 2 days, and y number of jumping jacks on the third day. Which equation can be used to find y, the number of jumping jacks Marcus completed on the third day? A.y = 187 + (60 × 2) B.y = 187 − (60 × 2) C.y = 187 − (60 ÷ 2) D.y = 187 + (60 ÷ 2)

Answer 1

187 jumping jacks in total
60 for each of the first 2 days
y=number of jumping jacks on day 3
187=y+2(60)
187-2(60)=y
Solution: B. y=187-(60×2)
