Shelly took out a payday loan for $750 due in 4 weeks that charged a $90 fee. What is the periodic interest rate of the loan?

OpenStudy (lstrasmann):

\[I = Prt\]

OpenStudy (anonymous):

I dont get what goes where into the eequation

OpenStudy (lstrasmann):

\[840 = 750 \times r \times .083\]That should be the right equation, if they are talking about monthly interest.

OpenStudy (lstrasmann):

Solve for r

OpenStudy (anonymous):

It has to be 48% 156% 624% or 12% and I didnt get any of those from doing it that way

OpenStudy (anonymous):

OpenStudy (lstrasmann):
