You were recently hired to replace the manager of the Roller Division at a major conveyor-manufacturing firm, despite the manager's strong external sales record. Roller manufacturing is relatively simple, requiring only labor and a machine that cuts and crimps rollers. As you begin reviewing the company's production information, you learn that labor is paid $11 per hour and the last worker hired produced 105 rollers per hour. The company rents roller cutters and crimping machines for $16 per hour, and the marginal product of capital is 120rollers per hour.

Should you change the mix of capital and labor, and if so, how should it change?

You should increase labor and decrease capital.
