Since Wesley and Billy each bought a jacket at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Wesley and Billy
= 4 u - 1 u
= 3 u
3 u = 138 - 87
3 u = 51
1 u = 51 ÷ 3 = 17
Amount that each of them paid for the jacket
= 87 - 17
= $70
Answer(s): $70
