The amount that Barbara and Sean 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 Barbara and Sean had at first
= 8 u + 10 u
= 18 u
18 u = 36
1 u = 36 ÷ 18 = 2
Total amount that Barbara and Sean spent
= 3 u + 5 u
= 8 u
= 8 x 2
= $16
Answer(s): $16
