Since Ben and Sam each bought a cardigan at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Ben and Sam
= 4 u - 1 u
= 3 u
3 u = 148 - 100
3 u = 48
1 u = 48 ÷ 3 = 16
Amount that each of them paid for the cardigan
= 100 - 16
= $84
Answer(s): $84
