Am I right?

OpenStudy (anonymous):

C?

OpenStudy (anonymous):

you multiply the investment by the interest rate

OpenStudy (anonymous):

What do you get?

OpenStudy (whpalmer4):

With simple interest (no compounding), FV = PV * n * (1+i) where FV = future value, PV = present value, n = number of periods, and i is the interest rate, expressed as a decimal (10% = 0.1). 1 year of interest at 4% on principal of $5500 = 0.04*5500 = $220. 5 years of interest would be 5*$220 = ?

OpenStudy (whpalmer4):

sorry, wrong formula in there! FV = PV + PV*n*i

OpenStudy (anonymous):

am i wrong?

OpenStudy (whpalmer4):

no, C is correct...

OpenStudy (anonymous):

ok.. what does V stand for in the formula?

OpenStudy (whpalmer4):

oh, PV = present value, FV = future value not a separate variable, just a two-letter name

OpenStudy (anonymous):

O, thanks

OpenStudy (whpalmer4):

got any others?

OpenStudy (anonymous):

OpenStudy (anonymous):
