Since Ryan and Rael each bought a sweater at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Ryan and Rael
= 3 u - 1 u
= 2 u
2 u = 121 - 93
2 u = 28
1 u = 28 ÷ 2 = 14
Amount that each of them paid for the sweater
= 93 - 14
= $79
Answer(s): $79
