Difference in the amounts between Barbara and Nora
= 8 p - 5 p
= 3 p
Since both Barbara and Nora spent an equal amount, the difference in the amounts that Barbara and Nora had at first and in the end remains unchanged.
3 p = 9
1 p = 9 ÷ 3 = 3
Amount that Barbara had left
= 8 p
= 8 x 3
= $24
Answer(s): $24
