Question

Jack and Walter work in a store's gift-wrapping department. Jack can wrap 28 boxes in 2 hours, while Walter takes 3 hours to wrap 36 boxes of the same size. One day they work together for t hours to gift wrap 65 boxes. Which equation models this situation?

A. 65=28+36/t
B. 65=26/t
C. 26t=65
D. 5t=65

Answer 1

C.

Explanation:

Jack's rate = 28/2 = 14 boxes/hour

Walter's rate = 36/3 = 12 boxes/hour

Combined rate = 14 + 12

= 26 boxes/hour

26 = 65/t

26t = 65
