he diagram displays short-run cost curves for a facility that produces liquid crystal display (LCD) creens for cell phones. a. The daily total fixed costs of producing LCD screens are s (Round to the nearest cent as needed.) b. The total variable costs of producing 50LCD screens per day are $ (Round to the nearest cent as needed.) c. The total costs of producing 50 LCD screens per day are $ (Round to the nearest cent as needed.) d. The marginal cost of producing 50LCD screens instead of 49 is $. (Hint To answer this question, you must first determine the total costs-or, altematively, the total variable costs - of producing 49 LCD screens.) (Round to the nearest cent as needed.).
