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):

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

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.

$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
