Kelly is a lawyer and also an excellent typist. She can type 120 words per minute but she has all the legal work she can handle at $75 per hour. Kelly's friend Todd works as a waiter earning $25 per hour. Todd would like some typing work but can only type only 60 words per minute. What is the most efficient scenario?

Question

Quizplus · Accepted Answer

To determine the most efficient scenario, we need to compare the earnings of Kelly and Todd in each scenario.

If Kelly does all the typing, she can earn $75 per hour. However, if Todd does the typing, he can earn a maximum of $60 per hour (60 words per minute at $1 per minute). Therefore, it is not efficient for Kelly to have Todd do the typing for her and pay him $20 per hour.

Since Todd's typing speed is slower than Kelly's, it is not efficient for him to become a full-time typist. However, he can still earn more than his hourly wage as a waiter by doing some typing work for Kelly.

If Todd does the typing, he will earn between $25 and $37.50 per hour (depending on the agreed-upon rate per word). As long as Todd's earnings from typing are within this range, it is efficient for him to do the typing work.

Therefore, the best choice is D: Todd should do the typing as long as his earnings are more than $25 and less than $37.50 per hour.
