Difference in the amounts between Penelope and Victoria
= 7 p - 5 p
= 2 p
Since both Penelope and Victoria spent an equal amount, the difference in the amounts that Penelope and Victoria had at first and in the end remains unchanged.
2 p = 12
1 p = 12 ÷ 2 = 6
Amount that Victoria had left
= 5 p
= 5 x 6
= $30
Answer(s): $30
