Since Peter and Simon each bought a blouse at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Peter and Simon
= 4 u - 1 u
= 3 u
3 u = 114 - 54
3 u = 60
1 u = 60 ÷ 3 = 20
Amount that each of them paid for the blouse
= 54 - 20
= $34
Answer(s): $34
