Answer:
option (A) Alex
Explanation:
Data provided in the question;
Earnings per hour of Becky = $120
Earnings per hour of Alex = $15
Hours taken to complete the task by Becky = 1 hour
Hours taken to complete the task by Alex = 6 hours
Now,
The opportunity cost for Becky
= Earnings per hour × Time taken to complete the task
= $120 × 1
= $120
and,
The opportunity cost for Alex
= Earnings per hour × Time taken to complete the task
= $15 × 6
= $90
Therefore,
The opportunity cost for the Alex is lowest
Hence, The correct answer is option (A) Alex
