The break-even point of your small business is the point at which your revenues equal your costs. this means that the amount of money that you make is equal to the amount of money that you are spending. profit is zero at the break-even point. study the curves for revenue, r(x), and costs, c(x). based on the current data, how many units represent the break-even point of your business? how does the value compare with the value you found in part b? what are the values for r(x) and c(x) at the break-even point? assume m = $40, b = $8,000, and d = $125.
