Difference in the amounts between Julie and Irene
= 5 p - 3 p
= 2 p
Since both Julie and Irene spent an equal amount, the difference in the amounts that Julie and Irene had at first and in the end remains unchanged.
2 p = 14
1 p = 14 ÷ 2 = 7
Amount that Irene had left
= 3 p
= 3 x 7
= $21
Answer(s): $21
