If the policy premium on a 30 year $500,000 term life policy for a 35 year old female is decreased to $361, what is the percent
Nady [450]

Answer:

The percentage decrease in price is 21.43

Step-by-step explanation:

Given as :

the policy amount fro 35 years = $500,000

The time period of policy is 35 years

The Amount decreased = $361

Let The percentage decrease = R %

Now, <u>From compounded method</u>

Amount after n years = initial amount × (1-\frac{Rate}{100})^{n}

or, $361 =  $500,000 × (1-\frac{Rate}{100})^{30}

Or, \frac{361}{500000} = (1-\frac{Rate}{100})^{30}

or, 0.000722 = (1-\frac{Rate}{100})^{30}

Or, 0.000722^{\frac{1}{30}} = 1-\frac{Rate}{100}

or, 0.7857 =  1-\frac{Rate}{100}

So, \frac{Rate}{100} = 1- 0.7857 = 0.2143

So, Decrease rate of interest = 21.43

Hence The percentage decrease in price is 21.43 Answer
