Difference in the amounts between Kathy and Nora
= 5 p - 3 p
= 2 p
Since both Kathy and Nora spent an equal amount, the difference in the amounts that Kathy and Nora had at first and in the end remains unchanged.
2 p = 22
1 p = 22 ÷ 2 = 11
Amount that Kathy had left
= 5 p
= 5 x 11
= $55
Answer(s): $55
