Difference in the amounts between Eva and Joelle
= 5 p - 3 p
= 2 p
Since both Eva and Joelle spent an equal amount, the difference in the amounts that Eva and Joelle had at first and in the end remains unchanged.
2 p = 22
1 p = 22 ÷ 2 = 11
Amount that Eva had left
= 5 p
= 5 x 11
= $55
Answer(s): $55
