Explanation:
As per the statement:
Quinton bought x number of shares for p dollars and paid a 1% commission
⇒He brought =
![0.01xp](https://img.qammunity.org/2020/formulas/mathematics/middle-school/vrvdo6nbutyfksgmpklivykcgzs3yaf2xo.png)
It is also given that he sold the stock for y dollars and paid a flat fee of $7.
⇒He sold =
![y-7](https://img.qammunity.org/2020/formulas/mathematics/high-school/z2ae4cznkh3whqxz2h20g01si66j3giho5.png)
then;
Net proceed is given as:
![y-7-0.01xp = y-(0.01xp+7)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/of5pqtbn8w4x61ciqrvna5uzihqvryj276.png)
Therefore, quintons net proceeds algebraically is
![y-(0.01xp+7)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/p5na8ym618za6nd532ywcjpfyl3e3guxx7.png)
