A small company that shovels sidewalks and driveways has 100 homes signed up for its services this winter. It can use various combinations of capital and labor: intensive labor with hand shovels, less labor with snow blowers, and still less labor with a pickup truck that has a snowplow on front. To summarize, the method choices are: Method 1: 50 units of labor, 10 units of capital Method \(2 : 20\) units of labor, 40 units of capital Method \(3 : 10\) units of labor, 70 units of capital If hiring labor for the winter costs \(\$ 100 /\) unit and a unit of capital costs \(\$ 400,\) what is the best production method? What method should the company use if the cost of labor rises to \(\$ 200 /\) unit?
