John brought a stamp for his collection. He agreed to pay a lump sum of $4000 after 5 years. Until then, he pays 6% simple interest semiannually on the $4000. a) Find the amount of each semiannual interest payment. b) John sets up a sinking fund so that enought money will be present to pay off the $4000. He will make annual payments into the fund. the accound pays 8% compounded annually. Find the amound of each payment. a) is it m=2 n=5x2=10 i=0.06/2=0.03 P=4000 and sub in A=P(1+i)^n and then solve for A interest=A-P therefore A-4000 so the interest is $1374.67??? b) i found that the amount of each payment is $681.83???? I am not really sure about my answers.
