Difference in the amounts between Elyse and Irene
= 7 p - 5 p
= 2 p
Since both Elyse and Irene spent an equal amount, the difference in the amounts that Elyse and Irene had at first and in the end remains unchanged.
2 p = 24
1 p = 24 ÷ 2 = 12
Amount that Elyse had left
= 7 p
= 7 x 12
= $84
Answer(s): $84
