The amount that Jean and Reggie each had in the end is the same. Make the amount that each had in the end the same. LCM of 4 and 1 is 4.
Total amount that Jean and Reggie had at first
= 7 u + 12 u
= 19 u
19 u = 38
1 u = 38 ÷ 19 = 2
Total amount that Jean and Reggie spent
= 3 u + 8 u
= 11 u
= 11 x 2
= $22
Answer(s): $22
