Using the concept of profit, it is found that the function is:
[tex]P(s) = -s^2 + 75s - 2000[/tex]
Profit is revenue subtracted by cost, that is:
[tex]P(s) = R(s) - C(s)[/tex]
The revenue function is:
[tex]R(s) = 100s - s^2[/tex]
Fixed cost of $2,000 thus $25 for each sneaker, thus, the cost function is:
[tex]C(s) = 2000 + 25s[/tex]
Then, the profit function is:
[tex]P(s) = R(s) - C(s)[/tex]
[tex]P(s) = 100 - s^2 - (2000 + 25s)[/tex]
[tex]P(s) = -s^2 + 75s - 2000[/tex]
