3 p |
Difference in the amounts between Hilda and Jade
= 10 p - 7 p
= 3 p
Since both Hilda and Jade spent an equal amount, the difference in the amounts that Hilda and Jade had at first and in the end remains unchanged.
3 p = 15
1 p = 15 ÷ 3 = 5
Amount that Jade had left
= 7 p
= 7 x 5
= $35
Answer(s): $35
