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.
