just doesn't seem right. When I calculate the same info on my TI-83 Plus, it

comes up with a completely different number. The problem is: "Show the

present value of 15 annual payments made to you, each payment being for

$2000. Assume that the interest rate is 7.5% per year and that the first

payment is made 12 months from today." When I calculate using the PV

function, the answer is $266.67. But when I calculate on the TI-83 Plus, I

get $17,654.24. What is it that I'm doing wrong? Which is correct? I have to

show the formula used in my spreadsheet. Any help would be greatly

appreciated.
