Leo paid $2400 in interest on an amount borrowed for 10 years at a 4% annual simple interest rate. How much did Leo borrow?

OpenStudy (superflytyguy):

Do you know how to find 4% percent of 2400?

OpenStudy (anonymous):

no

OpenStudy (superflytyguy):

Okay thats fine 4% = 0.04 multiply 2400 x 0.04 for me

OpenStudy (superflytyguy):

whatcha get

OpenStudy (anonymous):

96

OpenStudy (anonymous):

u still typing?

OpenStudy (superflytyguy):

Sorry, I read the question wrong! 2400 WAS the interest! MEANING 2400 was the percentage!

OpenStudy (anonymous):

o ok

OpenStudy (superflytyguy):

That means after 10 years he owed $2400 hundred dollars 2400 dollars divided by 10 years = $240 $240 = The 4% interest rate.

OpenStudy (superflytyguy):

That means after 10 years he owed $2400 dollars

OpenStudy (anonymous):

thx

OpenStudy (anonymous):

thats it? to the problem

OpenStudy (superflytyguy):

We still don't know how much he borrowed

OpenStudy (anonymous):

ok

OpenStudy (superflytyguy):

If 240 = 4%, $240 plus 100% would be how much he owed. Hmm,

OpenStudy (anonymous):

$480

OpenStudy (superflytyguy):

that would be 8%

OpenStudy (anonymous):

so $240

OpenStudy (superflytyguy):

600% = 10% 6000 = 100% We got it!!! Woohoo!!!

OpenStudy (anonymous):

so it is $240

OpenStudy (superflytyguy):

http://quizzes.cc/metric/percentof.php?percent=4&of=6000 Look!

OpenStudy (superflytyguy):

He borrowed 6000 dollars

OpenStudy (superflytyguy):

240 was the interest rate

OpenStudy (anonymous):

o cool

OpenStudy (anonymous):

OpenStudy (superflytyguy):
