Since Zane and Paul each bought a shirt at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Zane and Paul
= 5 u - 1 u
= 4 u
4 u = 180 - 108
4 u = 72
1 u = 72 ÷ 4 = 18
Amount that each of them paid for the shirt
= 108 - 18
= $90
Answer(s): $90
