Difference in the amounts between Cindy and Cathy
= 8 p - 3 p
= 5 p
Since both Cindy and Cathy spent an equal amount, the difference in the amounts that Cindy and Cathy had at first and in the end remains unchanged.
5 p = 55
1 p = 55 ÷ 5 = 11
Amount that Cathy had left
= 3 p
= 3 x 11
= $33
Answer(s): $33
