To find opportunity cost, we need to compare the trade-offs each person makes when completing a task. Joachim takes 20 minutes to clean a bathroom and 30 minutes to wash a window, while Zane takes 30 minutes to clean a bathroom and 20 minutes to wash a window. Therefore, Joachim's opportunity cost for cleaning a bathroom is 1.5 windows washed (30 minutes divided by 20 minutes per window), while Zane's opportunity cost for cleaning a bathroom is 0.67 windows washed (20 minutes divided by 30 minutes per window). Comparing the two, we see that Zane has a lower opportunity cost for cleaning bathrooms, as he gives up fewer windows washed compared to Joachim. Therefore, the best choice is B, where Zane should clean the bathrooms as his opportunity cost for this task is lower.
