Since Xavier and Eric each bought a shirt at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Xavier and Eric
= 4 u - 1 u
= 3 u
3 u = 131 - 98
3 u = 33
1 u = 33 ÷ 3 = 11
Amount that each of them paid for the shirt
= 98 - 11
= $87
Answer(s): $87
