Difference in the amounts between Pamela and Xandra
= 8 p - 3 p
= 5 p
Since both Pamela and Xandra spent an equal amount, the difference in the amounts that Pamela and Xandra had at first and in the end remains unchanged.
5 p = 40
1 p = 40 ÷ 5 = 8
Amount that Pamela had left
= 8 p
= 8 x 8
= $64
Answer(s): $64
