Question

Alexis is a lawyer. She bills her clients $100 an hour for her services. She can also mow her lawn in 30 minutes. She can hire someone to mow her lawn who takes an hour. Of the following prices, which is the highest Alexis would pay someone to mow her lawn?
a. $99
b. $49
c. $29
d. Alexis would always mow her own lawn because she can do it faster

Answer 1

Answer:

b) $49

Step-by-step explanation:

The question here is not if Alexis can mow the lawn faster or slower than the person who hires (actually, the time that the person hired took to mow the lawn is irrelevant).

The important part is the time Alexis can save hiring someone:

• Alexis mow her lawn in 30 minutes.

• Alexis earns $100 an hour. Then 30 minutes of her time is worthy $50.

Then, paying $50 or less is a good choice for Alexis.

Therefore the answer is b) $49.
