The amount that Roshel and Justin each had in the end is the same. Make the amount that each had in the end the same. LCM of 5 and 1 is 5.
Total amount that Roshel and Justin had at first
= 8 u + 20 u
= 28 u
28 u = 252
1 u = 252 ÷ 28 = 9
Total amount that Roshel and Justin spent
= 3 u + 15 u
= 18 u
= 18 x 9
= $162
Answer(s): $162
