Since Valen and Harry each bought a sweater at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Valen and Harry
= 3 u - 1 u
= 2 u
2 u = 135 - 105
2 u = 30
1 u = 30 ÷ 2 = 15
Amount that each of them paid for the sweater
= 105 - 15
= $90
Answer(s): $90
