Difference in the amounts between Barbara and Linda
= 10 p - 3 p
= 7 p
Since both Barbara and Linda spent an equal amount, the difference in the amounts that Barbara and Linda had at first and in the end remains unchanged.
7 p = 28
1 p = 28 ÷ 7 = 4
Amount that Linda had left
= 3 p
= 3 x 4
= $12
Answer(s): $12
