Conan o'brien hosts the conan show and andy richter, his sidekick, writes for it. conan needs 4 hours to host a good show. it takes andy 10 hours to do the same. conan writes one usable joke in an hour, but andy needs 2 hours to do the same. if they both were given 10 hours, andy's opportunity cost of writing a single usable joke is: a. 0.2 unit of hosting. b. 0.25 unit of hosting. c. 0.5 unit of hosting. d. 1 unit of hosting.

A

Step-by-step explanation:

The opportunity cost is the alternative that a person sacrifices when another alternative is chosen. In this case, Andy can choose either to host a show or to write jokes. In hour he can make 1/2 jokes (because he needs 2 hours to write 1 joke) and in 1 hour he can also make 1/10 units of hosting (because he needs 10 hours to host one good show). If he decides to make one joke, he will spend 2 hours, in which he could host 2/10 (2*(1/10)) shows. Then, Andy´s opportunity cost is 0.2 units of hosting
