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, From compounded method
Amount after n years = initial amount × [tex](1-\frac{Rate}{100})^{n}[/tex]
or, $361 = $500,000 × [tex](1-\frac{Rate}{100})^{30}[/tex]
Or, [tex]\frac{361}{500000}[/tex] = [tex](1-\frac{Rate}{100})^{30}[/tex]
or, 0.000722 = [tex](1-\frac{Rate}{100})^{30}[/tex]
Or, [tex]0.000722^{\frac{1}{30}}[/tex] = [tex]1-\frac{Rate}{100}[/tex]
or, 0.7857 = [tex]1-\frac{Rate}{100}[/tex]
So, [tex]\frac{Rate}{100}[/tex] = 1- 0.7857 = 0.2143
So, Decrease rate of interest = 21.43
Hence The percentage decrease in price is 21.43 Answer
