Difference in the amounts between Penelope and Wendy
= 8 p - 3 p
= 5 p
Since both Penelope and Wendy spent an equal amount, the difference in the amounts that Penelope and Wendy had at first and in the end remains unchanged.
5 p = 15
1 p = 15 ÷ 5 = 3
Amount that Penelope had left
= 8 p
= 8 x 3
= $24
Answer(s): $24
