Question 510289
you almost have the right formula


A = P(1 + r)^t ___ where r is the rate per compounding period and t is the number of periods


ann ___ 100000 = P(1 + .085)^13


semi ___ 100000 = P(1 + .0425)^26


qrt ___ 100000 = P(1 + .02125)^52


these involve exponents and will need to be solved using logs


for the 1st one ___ log(100000) = log(P) + 13[log(1.085)]
