The amount that Raeann and Justin each had in the end is the same. Make the amount that each had in the end the same. LCM of 2 and 1 is 2.
Total amount that Raeann and Justin had at first
= 5 u + 4 u
= 9 u
9 u = 72
1 u = 72 ÷ 9 = 8
Total amount that Raeann and Justin spent
= 3 u + 2 u
= 5 u
= 5 x 8
= $40
Answer(s): $40
