Question

Andrew is home one winter day studying for an exam. It is lunchtime and he is hungry. Instead of making a sandwich from roast beef in the fridge, he drives to Taco Bell and spends $4 for 2 tacos, a burrito and a Dr. Pepper. He reasons that he can make $10 per hour cutting lawns so he really saves $6 by going to Taco Bell rather than preparing his own meal. What's wrong with Andrew's argument?

Answer 1

Instead of spending time making food, he drives and buys food by a total of $4.

Now, he is not considerating the amount of gas that he is spending by going to buy food and returning.

Also, he was not working, so he is not producing money at the beginning, so making his own lunch actually does not implies that he stops working and loses money.

Answer 2

Andrew did not reason that he could save the $10 per hour he would make cutting lawns by preparing his own meal

Explanation:

If Andrew cuts lawns for $10 per hour, he would have $4 more to save by preparing his own meal rather than spending the $4 at Taco Bell
