Homework Help: Math

Posted by Finding Interest Rate in Interest Problems on Wednesday, April 25, 2007 at 6:32pm.

How do I do this? -- can anyone give me a formula to find the answers?


Find the annual rate of simple interest~
P: 5000 / I: 650 / T: 3 years.

PV = nRT

I=PRT so solving for R
we get R=I/(PT)

plug in your values and evaluate.
Your answer will be a decimal which you have to convert to a percentage.

e.g. if your answer would be 0.038, the interest rate would be 3.8% (move the decimal 2 places to the right)

ignore this formula...sorry

actual formula is:
I = Prt

where I = interest, P = principle, r = rate, t = time in years

Thank you all very much!!
