The amount that Gwen and Dylan each had in the end is the same. Make the amount that each had in the end the same. LCM of 5 and 1 is 5.
Total amount that Gwen and Dylan had at first
= 7 u + 25 u
= 32 u
32 u = 192
1 u = 192 ÷ 32 = 6
Total amount that Gwen and Dylan spent
= 2 u + 20 u
= 22 u
= 22 x 6
= $132
Answer(s): $132
