The amount that Nicole and Vincent 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 Nicole and Vincent had at first
= 5 u + 15 u
= 20 u
20 u = 160
1 u = 160 ÷ 20 = 8
Total amount that Nicole and Vincent spent
= 2 u + 12 u
= 14 u
= 14 x 8
= $112
Answer(s): $112
