| After |
5 p |
3 p |
2 p |
Difference in the amounts between Erika and Anna
= 5 p - 3 p
= 2 p
Since both Erika and Anna spent an equal amount, the difference in the amounts that Erika and Anna had at first and in the end remains unchanged.
2 p = 8
1 p = 8 ÷ 2 = 4
Amount that Erika had left
= 5 p
= 5 x 4
= $20
Answer(s): $20
