Difference in the amounts between Elyse and Cathy
= 8 p - 3 p
= 5 p
Since both Elyse and Cathy spent an equal amount, the difference in the amounts that Elyse and Cathy had at first and in the end remains unchanged.
5 p = 40
1 p = 40 ÷ 5 = 8
Amount that Cathy had left
= 3 p
= 3 x 8
= $24
Answer(s): $24
