After |
5 p |
3 p |
2 p |
Difference in the amounts between Nicole and Gwen
= 5 p - 3 p
= 2 p
Since both Nicole and Gwen spent an equal amount, the difference in the amounts that Nicole and Gwen had at first and in the end remains unchanged.
2 p = 10
1 p = 10 ÷ 2 = 5
Amount that Nicole had left
= 5 p
= 5 x 5
= $25
Answer(s): $25
