The amount that Lucy and George each had in the end is the same. Make the amount that each had in the end the same. LCM of 2 and 1 is 2.
Total amount that Lucy and George had at first
= 3 u + 12 u
= 15 u
15 u = 135
1 u = 135 ÷ 15 = 9
Total amount that Lucy and George spent
= 1 u + 10 u
= 11 u
= 11 x 9
= $99
Answer(s): $99
