The amount that Fanny and Sean each had in the end is the same. Make the amount that each had in the end the same. LCM of 4 and 1 is 4.
Total amount that Fanny and Sean had at first
= 7 u + 8 u
= 15 u
15 u = 75
1 u = 75 ÷ 15 = 5
Total amount that Fanny and Sean spent
= 3 u + 4 u
= 7 u
= 7 x 5
= $35
Answer(s): $35
