Geraldo's current salary is $40,000 per year. His annual pay raise is always a percent of his salary at the time.
What would his salary be if he got four consecutive 4% increases?
Round any decimals to the nearest cents.
:
Use the formula: A = P*%281%2B%28r%2Fn%29%29%5E%28nt%29
where
A = accumulated amt after t yrs
P = principal
r = interest rate in decimals
n = no. of compounding times per year
t = time in yrs
Since this is an annual raise, we can write it
A = P%2A%281%2Br%29%5Et
A = 40000%281%2B.04%29%5E4
A = 40000%2A1.04%5E4
using a calc we get
A = $46,794.34 after 4 yrs with an annual 4% raise
