Since Michael and Billy each bought a sweater at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Michael and Billy
= 4 u - 1 u
= 3 u
3 u = 119 - 68
3 u = 51
1 u = 51 ÷ 3 = 17
Amount that each of them paid for the sweater
= 68 - 17
= $51
Answer(s): $51
