Since Xavier and Sean each bought a blouse at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Xavier and Sean
= 4 u - 1 u
= 3 u
3 u = 122 - 77
3 u = 45
1 u = 45 ÷ 3 = 15
Amount that each of them paid for the blouse
= 77 - 15
= $62
Answer(s): $62
