Difference in the amounts between Nicole and Kathy
= 10 p - 7 p
= 3 p
Since both Nicole and Kathy spent an equal amount, the difference in the amounts that Nicole and Kathy had at first and in the end remains unchanged.
3 p = 27
1 p = 27 ÷ 3 = 9
Amount that Nicole had left
= 10 p
= 10 x 9
= $90
Answer(s): $90
