4. Production Possibility Frontier

An economy consists of three workers: Andrew, Darnell, and Jacques. Each works 10 hours a day and can produce two services: mowing lawns and washing cars. In an hour, Andrew can either mow 1 lawn or wash 1 car; Darnell can either mow 1 lawn or wash 2 cars; and Jacques can either mow 2 lawns or wash 1 car.

For each of the scenarios listed in the following table, determine how many lawns will be mowed and how many cars will be washed per day and enter these values into the corresponding row.
