Since Albert and Harry each bought a sweater at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Albert and Harry
= 3 u - 1 u
= 2 u
2 u = 108 - 70
2 u = 38
1 u = 38 ÷ 2 = 19
Amount that each of them paid for the sweater
= 70 - 19
= $51
Answer(s): $51
