Making Financial Calculations Easy 13
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
$45.00 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.
This is only a small sampling of the many financial calculations that can now be
done easily with your HP 12C Platinum. To begin learning about this powerful
