Rose production is perfectly competitive, and all rose growers have the same costs.

The market price of roses is $12 per bunch, and each producer maximizes profit by producing 20 bunches per day. Average total cost is $20 per bunch, and average variable cost is $10 per bunch.

1. Each grower's marginal cost of producing the 20th bunch of roses per day is $ .
2. If the price of roses falls, the largest possible economic loss a rose grower can incur (if they are maximizing profit) is $ per day.
