The amount that Xandra and Fabian 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 Xandra and Fabian had at first
= 3 u + 12 u
= 15 u
15 u = 150
1 u = 150 ÷ 15 = 10
Total amount that Xandra and Fabian spent
= 1 u + 10 u
= 11 u
= 11 x 10
= $110
Answer(s): $110
