OpenStudy (anonymous):

Compound or Simple?

OpenStudy (anonymous):

Could you explain how to do it? Cause I have no idea even what its talking about

OpenStudy (anonymous):

Oky CompoundInterest is the slightly complicated one. Its the one used in banks and stuff. Simple Interest is well pretty simple, Use a formula. Simple Interest = Principal x Rate x Time/100

OpenStudy (anonymous):

So you tell me. By simple interest what should be the answer.? And Interest is basically a charge charged on loans. It is computed using that formula I wrote.

OpenStudy (anonymous):

Would it be 10?

OpenStudy (anonymous):

Yes. Good. So 10$ is the Interest in simple interest. However. Peopleas you know make things complicated. So we have copound interest. Now it may look complex,but its really simple once you e hold of it. So we hae another formula. Amount= Principal x [ 1+ Rate/100] ^Time..

OpenStudy (anonymous):

**have a hold of it

OpenStudy (anonymous):

Okay thanks you soo much!

OpenStudy (anonymous):

So Interest is the surplus charge.Thereforeit'll be Amount - Principal.

So this one would be the same rite? : Compute the interest. Round to the nearest cent. Principal = $240 Rate = 12% per year Time = 2 Year Interest = _____

OpenStudy (anonymous):

I = prt = 100 * .1 = $10

OpenStudy (anonymous):

Chlorophyll, That was the answer for the first question rite?

OpenStudy (anonymous):

Yep!

OpenStudy (anonymous):

K thanks :)

OpenStudy (anonymous):

I = 240 *.12 * 2 = $57.6

OpenStudy (anonymous):

So you don't divide 100 at the end?

OpenStudy (anonymous):

She did. Made 12/100=0.12

OpenStudy (anonymous):

Ohh lol okay
