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

Question

A. 41
B. 1,307
C. 67
D. 622

Is it B or D??

Answer 1

what, no calculator?

Since 2015 is 5 years from 2010, you want to evaluate

32 * 2.1^5 = 1306.9

D should have been clearly wrong, since 2^5=32, so 32*32 = 1024 would be a good guess, though somewhat low.

Answer 2

-3x+9=-16+2x
