You can put this solution on YOUR website!
Let x = number of notebooks sold

Each notebook sells for $5. So they earn 5x dollars for selling x notebooks.

Profit: 5x + (-100) = 5x - 100

The profit equation is P = 5x - 100

-------------------------------------------------------

Breakeven point:


P = 5x - 100

0 = 5x - 100 ... at the breakeven point, the profit is $0, so P = 0

5x - 100 = 0

5x = 100

x = 100/5

x = 20

You need to sell 20 notebooks to break even. This is where you do not lose or gain money. You profit $0.

If you sell more than 20 notebooks, then your profit is positive. So the goal is to sell more than 20 notebooks to make this fundraiser worthwhile.
