Since Harry and Elijah each bought a blouse at the same price, the difference in the amounts each had remains the same.
Difference in the amounts between Harry and Elijah
= 4 u - 1 u
= 3 u
3 u = 108 - 72
3 u = 36
1 u = 36 ÷ 3 = 12
Amount that each of them paid for the blouse
= 72 - 12
= $60
Answer(s): $60
