7 p |
10 p |
3 p |
Difference in the amounts between Hilda and Esther
= 10 p - 7 p
= 3 p
Since both Hilda and Esther spent an equal amount, the difference in the amounts that Hilda and Esther had at first and in the end remains unchanged.
3 p = 6
1 p = 6 ÷ 3 = 2
Amount that Esther had left
= 7 p
= 7 x 2
= $14
Answer(s): $14
