Since Rael and Vaidev each bought a jacket at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Rael and Vaidev
= 4 u - 1 u
= 3 u
3 u = 87 - 51
3 u = 36
1 u = 36 ÷ 3 = 12
Amount that each of them paid for the jacket
= 51 - 12
= $39
Answer(s): $39
