An economy consists of three workers: Sam, Andrew, and Darnell. Each works 10 hours a day and can produce two services: mowing lawns and washing cars. In an hour, Sam can either mow 1 lawn or wash 1 car; Andrew can either mow 1 lawn or wash 2 cars; and Darnell can either mow 2 lawns or wash 1 car. For each of the scenarios listed, determine how many lawns will be mowed and how many cars will be washed per day and enter these values into the corresponding row.

a. All three spend all their time mowing lawns.

b. All three spend all their time washing cars.

c. All three spend half their time on each activity.

d. Sam spends half his time on each activity, while Andrew only washes cars and Darnell only mows lawns.

Special order carson manufacturing, inc., sells a single product for $36 per unit. at an operating level of 8,000 units, variable costs are $18 per unit and fixed costs $10 per unit. carson has been offered a price of $20 per unit on a special order of 2,000 units by big mart discount stores, which would use its own brand name on the item. if carson accepts the order, material cost will be $3 less per unit than for regular production. however, special stamping equipment costing $4,000 would be needed to process the order; the equipment would then be discarded. assuming that volume remains within the relevant range, prepare an analysis of differential revenue and costs to determine whether carson should accept the special order. use a negative sign with answer to only indicate an income loss from special order; otherwise do not use negative signs with your answers.
