Question 207514
savings account has a balance of $4069.
 After 4 years what will the amount of interest be at 5% compounded quarterly?
:
Compound interest formula
A = Ao*(1+(r/n))^(nt)
where
A = final amt
Ao = initial amt (4069)
r = interest rate in decimals (.05)
n = time per yr (4)
t = no. of yrs (4)
:
A = {{{4069 * (1+(.05/4))^(4*4)}}}
:
A = {{{4069 * (1.0125)^(16)}}}
:
A = 4069 * 1.220
:
A = 4963.73; amt after 4 yrs
:
4963.73 - 4069 = $894.73 interest in 4 yrs
