The amount that Gabby and Henry 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 Gabby and Henry had at first
= 5 u + 9 u
= 14 u
14 u = 70
1 u = 70 ÷ 14 = 5
Total amount that Gabby and Henry spent
= 2 u + 6 u
= 8 u
= 8 x 5
= $40
Answer(s): $40
