Since Reggie and Riordan each bought a cardigan at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Reggie and Riordan
= 3 u - 1 u
= 2 u
2 u = 114 - 76
2 u = 38
1 u = 38 ÷ 2 = 19
Amount that each of them paid for the cardigan
= 76 - 19
= $57
Answer(s): $57
