Since Eric and Japheth each bought a cardigan at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Eric and Japheth
= 3 u - 1 u
= 2 u
2 u = 135 - 101
2 u = 34
1 u = 34 ÷ 2 = 17
Amount that each of them paid for the cardigan
= 101 - 17
= $84
Answer(s): $84
