Question

Michigan has a population of 10 million. Nebraska averages 25,488 births per year with a population of 1.95 million. If Nebraska was proportional to Michigan in births per year to population, how many births would Michigan expect to have? Round to the nearest whole number.

Answer 1

Given:

25,488 births per year for a population of 1.95 million

For a population of 10 million, the births per year expect are:

$\frac{25488}{x}=\frac{1.95}{10}$

And solve for x (number of birhts):

$\begin{gathered} 1.95\times x=10\times25488 \\ 1.95x=254880 \\ \frac{1.95}{1.95}x=\frac{254880}{1.95} \\ x=130707.69 \end{gathered}$

Round to the nearest whole number is 130708

Answer: 130,708 births per year
