| After |
5 p |
8 p |
3 p |
Difference in the amounts between Natalie and Eva
= 8 p - 5 p
= 3 p
Since both Natalie and Eva spent an equal amount, the difference in the amounts that Natalie and Eva had at first and in the end remains unchanged.
3 p = 21
1 p = 21 ÷ 3 = 7
Amount that Eva had left
= 5 p
= 5 x 7
= $35
Answer(s): $35
