A local library claims it has 2.73x103 books. If there are 42 people in the building, how many books per capita are there?
sveticcg [70]

Answer:

Per\ Capita = 64

Step-by-step explanation:

Given

Books = 2.7  * 10^3

Per\ Capita = \frac{Books}{People}

Substitute 2.7 * 10^3 for books and 42 for people

Per\ Capita = \frac{2.7 * 10^3}{42}

Per\ Capita = 64 (Approximated)

<em>Hence, the per capita is 64</em>
