Value of policy in 14 years.
Example 3:
The preceding example showed that the insurance policy will
provide about half the required amount. An additional amount must be set aside to
provide the balance (21,396.61 – 10,371.79 = 11,024.82). Suppose you make
monthly payments, beginning at the end of next month, into an account that pays
6% annually, compounded monthly. What payment amount would be required in
order to accumulate $11,024.82 in the 14 years remaining
?

Example 4:
Suppose you cannot find a bank that currently offers an account
with 6% annual interest compounded monthly, but you can afford to make $45
monthly payments. What is the minimum interest rate that will enable you to
accumulate the required amount
?
In this problem, we do not need to clear the previous financial data inside the
calculator, since most of it is unchanged from the preceding example.
