Business formulas - jy0013 - Aug-27-2017 So, I need to get each of these formulas with the numbers that are listed below and I believe I have figured out the first one, but, I'm not 100% sure where to go from here or with the other formulas. He helped me some with the first but now I'm stuck. Any help is welcomed! # Future Value of Annuity p = 1000 r = 2 / 100 n = 5 future_value = p*((1+(0.01*r)) ** n) print(round(future_value,2)) #$5,204.04 #FV of Annuity -Continuous Compounding CF = 1000 r = 6/100/12 t = 12 import math print(math.e) print (math.e ** 2) print (math.exp(2)) #Annuity (FV)-Solve for n FV= 19600 r = 5/100 p = 1000 print (math.log(math.exp(3))) #Annuity Payment PV = 100000 r = 5/100 n = 10 print (p) RE: Business formulas - nilamo - Aug-28-2017 Help us to help you. Are you getting errors? Or is your output not what you expected? In the second case, what output do you currently get, and what are you expecting to get? Business formulas more help needed!! - jy0013 - Aug-28-2017 So, this is the code that I have gotten together for each of the formulas. But i'm getting an error for line 5 and i'm not sure why. Any helpp? # future value of annuity p = 1000 r = 2/100 n = 5 FV= p ((1+r) ** n - 1/r) print(FV) #FV of annuity- continuous compounding CF= 1000 r = 6/100/12 t = 12 import math FV= CF * ((1 + (r/n)) ** (n*t)) print (FV) #Annuity (FV)- solve for n import math FV= 19600 r = 5/100 p = 1000 n = math.log(1 + FV*r / p) / math.log(1+r) print(n) # annuity payments PV= 100000 # how much r = 5/100 # interest rate n = 10 #how many years p = r * (PV) / ((1 + r) ** n - 1) print(p) Whoops, in line 5 im suppose to have a * in between the p and the rest of the formula. But, I'm still not getting the correct answers RE: Business formulas more help needed!! - sparkz_alot - Aug-28-2017 Please do not start new threads when they concern the same topic and code. As to the problem, what is the output you are getting and what output do you expect?
