Difference in the amounts between Roshel and Gwen
= 7 p - 5 p
= 2 p
Since both Roshel and Gwen spent an equal amount, the difference in the amounts that Roshel and Gwen had at first and in the end remains unchanged.
2 p = 22
1 p = 22 ÷ 2 = 11
Amount that Roshel had left
= 7 p
= 7 x 11
= $77
Answer(s): $77
