Question 963360: a town with 10000 residents is losing .3% of the population per month due to a poor economy. I need to come up with a equation to see how many they lose in one year and then in every year for 10 years. I can't use my calculator for the -0.003 so I am stumped.

Can't use the calculator, why?
First year:
10000%281-0.3%2F100%29=9970
Second year:
9970%281-0.3%2F100%29=10000%281-0.3%2F100%29%5E2=9940
So then for each year,
P%28n%29=10000%281-0.3%2F100%29%5En
highlight%28P%28n%29=10000%280.997%29%5En%29
Now use the calculator and calculate all the values from 3 to 10.
I'll do n=10.
P%2810%29=10000%280.997%29%5E10=10000%280.970402%29=9704
