# FINAL PROJECT
# The program ask for a user to enter the initial amount in a saving account,
#the interest rate, the nomber of years and the time interest if applicable.
# function to calculate total amount in the saving acount
def cal_saving_amount(p, r, t, n):

else:

amount=p*((1+(r/n))**(n*t))
