Multiple Choice Questions:

4. Ed's bakery can sell as many loaves of bread as it wishes for a price of $2 per loaf. To keep calculations simple, let us assume that Ed's only costs are hired labor. If Ed hires 1 worker, he can produce 200 loaves of bread per day. If Ed hires 2 workers, he can produce 350 loaves of bread per day. If he hires 3 workers, he can produce 450 loaves of bread per day. If he hires 4 workers, he can produce 480 loaves of bread per day. If he hires 5 workers, he can produce 500 loaves of bread per day, and if he hires 6 workers, he can produce 510 loaves of bread per day. If he hires 7 or more workers, he can still produce only 510 loaves of bread per day. If Ed increases his work crew from 4 workers to 5 workers, his daily revenue will increase by:
(a) $100
