Answer:
The answer is 605,183.
Explanation:
The aunt has to calculate how much money will cost an annuity of 50,000 for 30 years, at one rate of 7.25%, and she wants to star at the end od the first year. The formula we need is [tex]C * (1-(1+i)^{-t} )/i[/tex], where C is the annuity, i is the rate, and t is the amount of years of the annuity., So, the calculation is [tex]50,000 * (1-(1,0725)^{-30} )/0,0725 = 50,000 * 12,1036627 = 605,183[/tex].
