Since Glen and Zane each bought a cardigan at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Glen and Zane
= 3 u - 1 u
= 2 u
2 u = 136 - 96
2 u = 40
1 u = 40 ÷ 2 = 20
Amount that each of them paid for the cardigan
= 96 - 20
= $76
Answer(s): $76
