Question

McDonald's is the king of the burger world, as it has more hamburger joints than any other restaurant chain. In 2013, McDonald's had 14267 locations in the US. If the population of the US was approximately 316.5 million citizens in 2013, what was the number of McDonald's restaurants per capita in the US in 2013? Express your answer in scientific notation rounded correctly to three decimal places.

Answer 1

I believe the answer would be .0000451, or 4.51 x 10^-5 McDonald's per capita

Answer 2

It is given that in 2013, McDonald's had 14267 locations in the US. It is also given that the population of the US was approximately 316.5 million citizens in 2013. Now, we know that 316.5 million=316500000.

Therefore, in order to find the number of McDonald's restaurants per capita in the US in 2013 all that we have to do is divide the number of McDonald's restaurants in 2013 with the population of the same year.

Thus, we get, number of McDonald's restaurants per capita in the US in 2013 to be:

`(14267)/(316500000)\approx4.508*10^(-5)` (the answer has been expressed in scientific notation rounded correctly to three decimal) places.
