8 p |

5 p |
Difference in the amounts between Wendy and Diana
= 8 p - 3 p
= 5 p
Since both Wendy and Diana spent an equal amount, the difference in the amounts that Wendy and Diana had at first and in the end remains unchanged.
5 p = 20
1 p = 20 ÷ 5 = 4
Amount that Wendy had left
= 8 p
= 8 x 4
= $32
Answer(s): $32
