If julie invests $9,250 at a rate of 7%, compounded weekly, find the value of the investment after 5 years.

First, we determine the effective interest rate of the given compound interest. 
                            ieff = (1 + r/n)^n - 1
where r is the given original rate and n is the number of compounding. In a year, there are approximately 52 weeks. 
                              ieff = (1 + 0.07/52)^52 - 1
                              ieff = 0.07246 = 7.246%
Then, we calculate for the future worth of money after five years using the effective interest annually. 
                             F = P (1 + r)^n
Substituting,
                           F = ($9250)*(1 + 0.07246)^5 
                               = $13,123.29
Thus, the value of the investment after 5 years is approximately equal to $13,123.29. 

Ibelieve it would be letter c (:
