The annual interest rate is 6%; the monthly interest rate is 1/12 of that, which is 0.5%, or 0.005. So the investment grows by a factor of 1.005 8 times; the ending value is
Answer C.
As a multiple choice problem, you can determine the answer with some estimation and a bit of mental arithmetic.
If it were simple interest, 8 months (2/3 of a year) at 6% annual interest would earn 4% interest; 4% interest on $6600 is $264. $264 added to the initial investment is $6864; the final value with compound interest has to be very slightly higher than that.
