5 p |
8 p |
3 p |
Difference in the amounts between Rachel and Gwen
= 8 p - 5 p
= 3 p
Since both Rachel and Gwen spent an equal amount, the difference in the amounts that Rachel and Gwen had at first and in the end remains unchanged.
3 p = 15
1 p = 15 ÷ 3 = 5
Amount that Gwen had left
= 5 p
= 5 x 5
= $25
Answer(s): $25
