Difference in the amounts between Xandra and Elyse
= 7 p - 5 p
= 2 p
Since both Xandra and Elyse spent an equal amount, the difference in the amounts that Xandra and Elyse had at first and in the end remains unchanged.
2 p = 6
1 p = 6 ÷ 2 = 3
Amount that Elyse had left
= 5 p
= 5 x 3
= $15
Answer(s): $15
