4 p |
7 p |
3 p |
Difference in the amounts between Eva and Linda
= 7 p - 4 p
= 3 p
Since both Eva and Linda spent an equal amount, the difference in the amounts that Eva and Linda had at first and in the end remains unchanged.
3 p = 9
1 p = 9 ÷ 3 = 3
Amount that Linda had left
= 4 p
= 4 x 3
= $12
Answer(s): $12
