Answer:
The percentage decrease in price is 21.43
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 ×
![(1-(Rate)/(100))^(n)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/bmuelzi2nhno9uuuho8g84tynbyk4lgcas.png)
or, $361 = $500,000 ×
![(1-(Rate)/(100))^(30)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/7zf8cfoyev6ytnufl637irafx5dcm1urwo.png)
Or,
=
![(1-(Rate)/(100))^(30)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/7zf8cfoyev6ytnufl637irafx5dcm1urwo.png)
or, 0.000722 =
Or,
=
![1-(Rate)/(100)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/xir1figz7zxf18vk8jdgcf36kkj8smehms.png)
or, 0.7857 =
![1-(Rate)/(100)](https://img.qammunity.org/2020/formulas/mathematics/middle-school/xir1figz7zxf18vk8jdgcf36kkj8smehms.png)
So,
= 1- 0.7857 = 0.2143
So, Decrease rate of interest = 21.43
Hence The percentage decrease in price is 21.43 Answer
