5. Your friend has a job at a fast food restaurant wrapping hamburgers. How many

hamburgers will they have to wrap to make one million dollars?

Every 3 hours they wrap 350. hamburgers.

They work 8 hours per day; 5 days per week.

They are paid every 2 weeks with a salary of $725.77.

Each conversion factor has a value of 1, but changes units. That is, the value of the numerator is the same as the value of the denominator, but expressed in different units.

We choose the representation of the conversion factors to cancel units we don't want and give us units we do want.

[tex]\$1\,000\,000=\$1\,000\,000\times\dfrac{2\text{ week}}{\$725.77}\times\dfrac{5\text{ day}}{1\text{ week}}\times\dfrac{8\text{ h}}{1\text{ day}}\times\dfrac{350\text{ burgers}}{3\text{ h}}\\\\=\dfrac{1\,000\,000\times2\times5\times8\times350}{725.77\times3}\text{ burgers}\approx\boxed{12\,859\,905\text{ burgers}}[/tex]

That's a little over 55 years, if they take 2 weeks off each year.
