The amount that Shannon and Bryan 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 Shannon and Bryan had at first
= 7 u + 15 u
= 22 u
22 u = 220
1 u = 220 ÷ 22 = 10
Total amount that Shannon and Bryan spent
= 2 u + 10 u
= 12 u
= 12 x 10
= $120
Answer(s): $120
