5 p |

2 p |
Difference in the amounts between Diana and Natalie
= 7 p - 5 p
= 2 p
Since both Diana and Natalie spent an equal amount, the difference in the amounts that Diana and Natalie had at first and in the end remains unchanged.
2 p = 20
1 p = 20 ÷ 2 = 10
Amount that Natalie had left
= 5 p
= 5 x 10
= $50
Answer(s): $50
