The amount that Fiona and Liam 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 Fiona and Liam had at first
= 4 u + 18 u
= 22 u
22 u = 88
1 u = 88 ÷ 22 = 4
Total amount that Fiona and Liam spent
= 1 u + 15 u
= 16 u
= 16 x 4
= $64
Answer(s): $64
