7 p |

2 p |
Difference in the amounts between Esther and Winnie
= 7 p - 5 p
= 2 p
Since both Esther and Winnie spent an equal amount, the difference in the amounts that Esther and Winnie had at first and in the end remains unchanged.
2 p = 14
1 p = 14 ÷ 2 = 7
Amount that Esther had left
= 7 p
= 7 x 7
= $49
Answer(s): $49
