Difference in the amounts between Marion and Julie
= 5 p - 3 p
= 2 p
Since both Marion and Julie spent an equal amount, the difference in the amounts that Marion and Julie had at first and in the end remains unchanged.
2 p = 10
1 p = 10 ÷ 2 = 5
Amount that Marion had left
= 5 p
= 5 x 5
= $25
Answer(s): $25
