The amount that Zoe and Ahmad 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 Zoe and Ahmad had at first
= 5 u + 9 u
= 14 u
14 u = 42
1 u = 42 ÷ 14 = 3
Total amount that Zoe and Ahmad spent
= 2 u + 6 u
= 8 u
= 8 x 3
= $24
Answer(s): $24
