Si Fer ha decidido recibir la herencia en un plazo de 60 meses, ¿cuál de las mensualmente? expresiones representa el monto, en pesos, que recibirá A) \( \frac{250000000}{1-(51)^{-60}} \) B) \( \frac{2500000}{1-(1,5)^{-60}} \) C) \( \frac{250000}{1-(1,05)^{-60}} \) D) \( \frac{25000}{\text { D) }} \) Q-1: The Williams purchased a home for \( \$ 480,000 \). They made a \( 20 \% \) down payment and borrowed the rest at \( 5 \% \) interest compounded monthly on a 20 -year loan. Their monthly payments are \( \$ 2507.83 \).
