Question

Donny, of Donny's Doughnuts, bakes and sells 100 dozen doughnuts a day using one mixer and one fryer. His rival, Sunshine, of Sunshine's Doughnuts, produces 180 dozen doughnuts a day using two mixers and two fryers. Both shops use the exact same technology to make doughnuts and have the same number of workers and the same size building. Donny and Sunshine both increase their capital equipment by one mixer and one fryer

Which shop will benefit the most from its expansion?
A. The shops will benefit equally because they are using the same quantity of equipment.
B. Donny, because his workers currently have less available capital to work with
C. The local weight-loss clinic, because the number of doughnuts consumed will increase
D. Sunshine, because her operation was producing more doughnuts to start with
How much should Donny realistically expect his production to increase with the new equipment?
A. about 80 dozen
B. about 50 dozen
C. at least 100 dozen
How much should Sunshine realistically expect her production to increase with the new equipment?
A. about 50 dozen
B. at least 80 dozen
C. at least 100 dozen

Answer 1

Which shop will benefit the most from its expansion?

• B. Donny, because his workers currently have less available capital to work with

The law of marginal returns applies here, that is why Sunshine donuts didn't produce twice as many by using more machines

How much should Donny realistically expect his production to increase with the new equipment?

• A. about 80 dozen

Similar to the additional production that Sunshine had in the past.

How much should Sunshine realistically expect her production to increase with the new equipment?

• A. about 50 dozen

Maybe even a little more than 50 dozen, but definitely less than 80 or 100.
