7 p |
Difference in the amounts between Victoria and Kathy
= 10 p - 3 p
= 7 p
Since both Victoria and Kathy spent an equal amount, the difference in the amounts that Victoria and Kathy had at first and in the end remains unchanged.
7 p = 35
1 p = 35 ÷ 7 = 5
Amount that Kathy had left
= 3 p
= 3 x 5
= $15
Answer(s): $15
