Cash Flow Calculations96
How much should you pay for the contract if you wish to yield a yearly rate of 15% on your
investment?
Figure 6 Cash flow diagram (Calculate the amount)
The following example uses the Æ and ¤ keys to enter the cash flow amount and repeat
value simultaneously. When the cash flow count is 1 for a given cash flow amount, the cash
flow amount may be entered simply by pressing the amount followed by ¤, as the default
for the count is 1. However, when using the Æ key to enter the cash flow amount, you must
then follow Æwith the repeat value followed by ¤, even if the repeat value is 1. This
process is shown here to demonstrate this application and for consistency with entering the
data for the example.
