Since Ethan and Sean each bought a hoodie at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Ethan and Sean
= 4 u - 1 u
= 3 u
3 u = 100 - 55
3 u = 45
1 u = 45 ÷ 3 = 15
Amount that each of them paid for the hoodie
= 55 - 15
= $40
Answer(s): $40
