Because your 18 year-old friend never learned
dimensional analysis, he started working at
McDonald’s wrapping hamburgers. Every 3 hours
he wraps 350 hamburgers. He works 8 hours a
day and 5 days a week. He gets paid every 2
weeks with a salary of $440.34 (after taxes!)
Approximately how many hamburgers will he
have to wrap to make his first one million
dollars?
(If you can solve this problem, you know DA and maybe you
can help your friend get a better job! Round your answer
to one significant figure - it’s going to be LARGE!)
How much time will it take to wrap all those
hamburgers. Express the time in years. Assume
that he will work 40 weeks out of the year and
that he produces the same amount of wrapped
burgers every day.
By the way, be careful on this one – nobody
works 24 hours a day! Round your answer to the
nearest year.
