The amount that Elyse and Paul each had in the end is the same. Make the amount that each had in the end the same. LCM of 3 and 1 is 3.
Total amount that Elyse and Paul had at first
= 7 u + 12 u
= 19 u
19 u = 38
1 u = 38 ÷ 19 = 2
Total amount that Elyse and Paul spent
= 4 u + 9 u
= 13 u
= 13 x 2
= $26
Answer(s): $26
