The amount that Vanessa and Gabriel 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 Vanessa and Gabriel had at first
= 5 u + 8 u
= 13 u
13 u = 156
1 u = 156 ÷ 13 = 12
Total amount that Vanessa and Gabriel spent
= 3 u + 6 u
= 9 u
= 9 x 12
= $108
Answer(s): $108
