Difference in the amounts between Tiffany and Barbara
= 8 p - 3 p
= 5 p
Since both Tiffany and Barbara spent an equal amount, the difference in the amounts that Tiffany and Barbara had at first and in the end remains unchanged.
5 p = 50
1 p = 50 ÷ 5 = 10
Amount that Barbara had left
= 3 p
= 3 x 10
= $30
Answer(s): $30
