Question 1203219
Something is wrong with how you wrote the question.  You ask for two things or one thing?
You started in asking what is the interest rate.  


Maybe you have this:
What is the interest rate, comounded weekly if you want $3624.84 to grow to $4725 in 92 weeks?


r for weekly interest rate as decimal number


{{{3624.84(1+r)^92=4275}}}
Solve for r.
