Question

Answer:

I can help! Let's start with 1.
Your formula is r = n(ln(A/P)/(nt)) R being the interest rate of what your trying to find. So A= 3,634.51 P = 2,564.65 N is the number of times compounded per year.N= 2 and t is the number of years t= 13. Also while doing so use PEMDAS Let me know if you need any more help!
