The amount that Xylia and Peter 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 Xylia and Peter had at first
= 5 u + 9 u
= 14 u
14 u = 28
1 u = 28 ÷ 14 = 2
Total amount that Xylia and Peter spent
= 2 u + 6 u
= 8 u
= 8 x 2
= $16
Answer(s): $16
