I make cookies for $30 plus $0.50 per cookie for ingredients. We want to sell them for $2 each. How many would I need to make to break even

Let's denote the number of cookies you need to make to break even as x.

The cost of making x cookies is given by:

Cost = $30 + $0.50x

The revenue from selling x cookies is given by:

Revenue = $2x

For you to break even, the cost must equal the revenue:

$30 + $0.50x = $2x

Solving for x:

$30 = $2x - $0.50x
$30 = $1.50x
x = 20

Therefore, you would need to make and sell 20 cookies to break even.
