# Requests starting tuition and annual increase rate
# Converts string results to float type in order to use for calculations
year_one = float(input("Please input your starting tuition for year one: \n"))
annual_inc = float(input("Please input the annual increase rate of your tuition: \n"))

# Calculates tuition amounts for years 2-4 using increase rate and
# previous year's amount 
year_two = year_one + year_one * annual_inc
year_three = year_two + year_two * annual_inc
year_four = year_three + year_three * annual_inc

# Prints results for years 1-4 and total tuition for all 4 years
print("\nYear one tuition: $" + str(format((year_one), '.2f')))
