Question

Let's think about billions by looking at Bill Gates, president of Microsoft. One year, his personal wealth grew by $20 billion. Suppose he was working by the hour, like working at a fast food place, but with a higher wage. Suppose he saw a $100 bill at his feet, if his salary were docked for the time it would take him to pick it up, should he stop work and take the time to pick up the $100 bill?

Answer 1

Answer:

No, he should not pick up the $100 bill

Explanation:

If his salary were those $20 billion (20,000,000,000) by a year. Let's find out how much this is by a second.

First let's find out how much is that salary by a day, then by an hour, then by a minute and finally by a second.

$\frac{20,000,000,000}{year}*(\frac{1 year}{365d})*(\frac{1d}{24h})*(\frac{1}{60min} )*(\frac{1min}{60s} ) \\\\ =\frac{20,000,000,000}{365*24*60*60} \\ \\ =\frac{20,000,000,000}{31,536,000} \\ \\ =634.19$

So he would be losing money if he picks up the $100 bill, because he would be missing 634 dollars per second.
