21. Kick Back is producing a new hammock. For the first year, its fixed costs for setting up production are $40,000. The variable costs of producing each hammock are $25. Each hammock will sell for $70. For Kick Back's first year, find the following for production of x hammocks. a. its profit function (Profit is the difference of revenue received and costs incurred.) b. its break-even production level (Break-even level occurs when costs equal revenue.) c. its net profit from the production of 300 hammocks
