Lucia and kenji need to decide which one of them will take time off from work to complete the rather urgent task of shearing their llamas. lucia is pretty good with a pair of shears; she can shear the llamas in 1 hour. kenji is somewhat slow; it takes him 4 hours to shear the llamas. lucia earns $120 per hour as a psychiatrist, while kenji earns $20 per hour as a cobbler.
keeping in mind that either lucia or kenji must take time off from work to shear the llamas, who has the lowest opportunity cost of completing the task?
a. lucia and kenji face identical opportunity costs
b. kenji
c. lucia
