Since Oliver and Xavier each bought a sweater at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Oliver and Xavier
= 5 u - 1 u
= 4 u
4 u = 145 - 85
4 u = 60
1 u = 60 ÷ 4 = 15
Amount that each of them paid for the sweater
= 85 - 15
= $70
Answer(s): $70
