'''Tengo esta tarea, se definieron 3 variables (balance, annualInterestRate y monthlyPaymentRate). Es para calcular cuanto se habra pagado de un prestamo al final de un año, si se paga con la tasa mas baja. En este caso los valores de prueba son: balance = 5000, annualInterestRate = 0.18 y monthlyPaymentRate = 0.02
El output es asi:
Month: 1 (para cada mes)
Minimum monthly payment: 96.0 (para cada mes)
Remaining balance: 4784.0 (para cada mes)
Total paid: 96.0 (al final del programa)
Remaining balance: 4784.0 (al final del programa)
En el idle me corre bien y genera los datos pero en el sistema de edx me da error.'''
