VF=500+120t Donde VF es el valor futuro y t es el tiempo en años, determine: a) La tasa de interés simple. B) El tiempo transcurrido para que el inversionista reciba $600 de interés total. C) Cuál es la deuda inicial del quito año si el banco prestamista no ah recibidos intereses de mora y no cobrar intereses de mora. • Se obtenía un préstamo de $1,000 durante tres años y el capital banquero cobraba 5% de interés anual compuesto. La pregunta fue: ¿Cuánto es el monto que paga el prestatario al final de los tres años?
