| After |
5 p |
7 p |
2 p |
Difference in the amounts between Sabrina and Natalie
= 7 p - 5 p
= 2 p
Since both Sabrina and Natalie spent an equal amount, the difference in the amounts that Sabrina and Natalie had at first and in the end remains unchanged.
2 p = 10
1 p = 10 ÷ 2 = 5
Amount that Natalie had left
= 5 p
= 5 x 5
= $25
Answer(s): $25
