10 p |

7 p |
Difference in the amounts between Hazel and Hilda
= 10 p - 3 p
= 7 p
Since both Hazel and Hilda spent an equal amount, the difference in the amounts that Hazel and Hilda had at first and in the end remains unchanged.
7 p = 14
1 p = 14 ÷ 7 = 2
Amount that Hazel had left
= 10 p
= 10 x 2
= $20
Answer(s): $20
