5 p |

2 p |
Difference in the amounts between Nicole and Zoe
= 7 p - 5 p
= 2 p
Since both Nicole and Zoe spent an equal amount, the difference in the amounts that Nicole and Zoe had at first and in the end remains unchanged.
2 p = 12
1 p = 12 ÷ 2 = 6
Amount that Zoe had left
= 5 p
= 5 x 6
= $30
Answer(s): $30
