at simple interest,
let the original be $x
change our times to months ---> 2 yrs, 3 months = 27 months
interest = x(.11)(27/24) = 99x/800
x+99x/800 = 4491
x(1 + 99/800)= 4491
x = 3996.44
in 3 years:
amount = 3996.44 + 3996.44(.11)(3)
= 5315.27
at compound interest:
original amount --- y
y(1.11)^(27/12) = 4491
y = 3551.13
after 3 years:
amount = 3551.13(1.11)^3
= 4856.63
