7 p |
Difference in the amounts between Esther and Xylia
= 10 p - 3 p
= 7 p
Since both Esther and Xylia spent an equal amount, the difference in the amounts that Esther and Xylia had at first and in the end remains unchanged.
7 p = 35
1 p = 35 ÷ 7 = 5
Amount that Esther had left
= 10 p
= 10 x 5
= $50
Answer(s): $50
