Answer 1

To evaluate the expression for the year 2015, we need to substitute x = 2015 - 2010 = 5 into the expression.

32 * 2.1^5 = 32 * 2.1^5 = 32 * 10.501

Rounding to the nearest whole number, we get:

32 * 10.501 ≈ 336

So, the population for the year 2015 is approximately 336,000.

Therefore, the closest option is 622.
