a $40,000 loan at 4 percent dated june 10 is due to be paid on October 11. What is the amount of simple interest? Show all work.

OpenStudy (anonymous):

right out the simple interest formula.

OpenStudy (anonymous):

i=P*r*t?

OpenStudy (anonymous):

yes, that is correct.

OpenStudy (anonymous):

now substitute the values of p(principle), r(rate) is in decimal and t(time) in years.

OpenStudy (anonymous):

I=40,000*.04*123

OpenStudy (anonymous):

where does the 123 come from?

OpenStudy (anonymous):

the difference from June 10 and October 11.

OpenStudy (anonymous):

ok, if you calculated that, I'm trusting you did that correctly. The last part would be times 123/366 because it is in years, and there is 365 days in a year.

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

then you should get your answer.

OpenStudy (anonymous):

ok gotcha

OpenStudy (anonymous):
