Profit Selling Sweatshirts
An equation can be written for a business to determine how much profit they will make.
For an example, your business began selling sweatshirts at a cost of $10. The first year you
sold 1,000 (great first year!). You decided to raise the selling price by $5 and found the
total number sold decreased by 100 sweatshirts (see the table below). It costs $10 to
produce 1 sweatshirt.

Using some algebra, you determine the equation to represent the relationship between the
selling price (s) and the profit (f(s)) (assuming you continue the trend of raising the price
by $5 and selling 100 less) is f(s)=-20s +1400s-12,000. Above is the graph of the
function.
