Since Michael 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 Michael and Tim
= 5 u - 1 u
= 4 u
4 u = 190 - 110
4 u = 80
1 u = 80 ÷ 4 = 20
Amount that each of them paid for the cardigan
= 110 - 20
= $90
Answer(s): $90
