The amount that Emma and John 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 Emma and John had at first
= 8 u + 15 u
= 23 u
23 u = 46
1 u = 46 ÷ 23 = 2
Total amount that Emma and John spent
= 3 u + 10 u
= 13 u
= 13 x 2
= $26
Answer(s): $26
