The number of employees for a certain company has been decreasing each year by 7%. If the company currently has 810 employees and this rate continues, find the number of employees in 9 years.

If the rate continues, in nine years there will be about 300 employees

The formula used is f(x)=a(1+r)^x so 7%(rate of change ) as a decimal is .07 +1 is 1.07 so we have 810(1.07)^9 because a is your initial amount so you multiply 1.07 by 9 according to PEMDAS and then take what you get there and multiply by 810 and you have your exponential growth
