The amount that Julie and Sean 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 Julie and Sean had at first
= 7 u + 12 u
= 19 u
19 u = 209
1 u = 209 ÷ 19 = 11
Total amount that Julie and Sean spent
= 3 u + 8 u
= 11 u
= 11 x 11
= $121
Answer(s): $121
