Since Luke and Owen each bought a skirt at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Luke and Owen
= 3 u - 1 u
= 2 u
2 u = 131 - 103
2 u = 28
1 u = 28 ÷ 2 = 14
Amount that each of them paid for the skirt
= 103 - 14
= $89
Answer(s): $89
