Since Zeph and Tim each bought a cardigan at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Zeph and Tim
= 4 u - 1 u
= 3 u
3 u = 98 - 62
3 u = 36
1 u = 36 ÷ 3 = 12
Amount that each of them paid for the cardigan
= 62 - 12
= $50
Answer(s): $50
