The amount that Shannon and Billy 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 Billy had at first
= 8 u + 15 u
= 23 u
23 u = 207
1 u = 207 ÷ 23 = 9
Total amount that Shannon and Billy spent
= 3 u + 10 u
= 13 u
= 13 x 9
= $117
Answer(s): $117
