Asked by Carmen

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.

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

Is it B or D??
Answered by Steve
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.

Be careful of these lists of answers without explanations. Sometimes kids deliberately post wrong answers. Sometimes teachers and/or test publishers mix the questions and answer choices up. Sometimes they change them completely!

Be aware!
