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