Suppose the growth of a population (in thousands) is represented by the expression 32 * 2.1x, where x represents the number of years since 2010. Evaluate the expression for the year 2015. Round to the nearest whole number.

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.
