Apoll has a percent error of 4%. the poll states 15,000 people will vote for candidate a in the next election. which statement describes what the actual number of people voting for candidate a could be? a. the actual number of people is either 9,000 or 21,000. b. the actual number of people is either 14,400 or 15,600. c. the actual number of people is either 14,423 or 15,625. d. the actual number of people is either 14,940 or 15,060.

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
