Question

11 multiple choice 1 point in 1950, scientists estimated a certain animal population in a particular geographical area had to be 6,400. in 2000, the population had risen to 7,200. if this animal population experiences the same percent increase over the next 50 years, what will the approximate population be? 8,000 8,400 8,600 8,100

Explanation:

Step1: Calculate percent increase

First, find the increase from 1950 to 2000. The increase is \( 7200 - 6400 = 800 \). The percent increase is \( \frac{800}{6400} \times 100\% = 12.5\% \) or \( 0.125 \).

Step2: Apply percent increase to 2000 population

The population in 2000 is 7200. To find the population after a 12.5% increase, we calculate \( 7200 \times (1 + 0.125) = 7200 \times 1.125 \).
\( 7200 \times 1.125 = 8100 \).

Answer:

8,100 (corresponding to the option with 8,100)
