Difference in the amounts between Penelope and Tina
= 7 p - 4 p
= 3 p
Since both Penelope and Tina spent an equal amount, the difference in the amounts that Penelope and Tina had at first and in the end remains unchanged.
3 p = 27
1 p = 27 ÷ 3 = 9
Amount that Penelope had left
= 7 p
= 7 x 9
= $63
Answer(s): $63
