3 p |
Difference in the amounts between Nicole and Gillian
= 10 p - 7 p
= 3 p
Since both Nicole and Gillian spent an equal amount, the difference in the amounts that Nicole and Gillian had at first and in the end remains unchanged.
3 p = 6
1 p = 6 ÷ 3 = 2
Amount that Nicole had left
= 10 p
= 10 x 2
= $20
Answer(s): $20
