Difference in the amounts between Emily and Roshel
= 10 p - 3 p
= 7 p
Since both Emily and Roshel spent an equal amount, the difference in the amounts that Emily and Roshel had at first and in the end remains unchanged.
7 p = 63
1 p = 63 ÷ 7 = 9
Amount that Emily had left
= 10 p
= 10 x 9
= $90
Answer(s): $90
