Since Nick and Luis each bought a cardigan at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Nick and Luis
= 3 u - 1 u
= 2 u
2 u = 113 - 85
2 u = 28
1 u = 28 ÷ 2 = 14
Amount that each of them paid for the cardigan
= 85 - 14
= $71
Answer(s): $71
