M	10,371.79 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.
