Stock in 1999 your parents bought $3000 worth of stock. in 2000 the value of the stock jumped to $6000. however since that time, the stock has decreased in value by 6.5% per year. write an exponential decay model to describe the worth of the stock, where t=0 corresponds to 2000. what do you expect the value of that stock to be in 2015 if the rate of decay remains 6.5% per year?

month 1 start amount =$3287.90 interest=(3287.90x0.0145/12)3.97 total to pay=$3291.81 paid =$1200 balance =$2,091.87

month 2 starting amount= $2,091.87 interest =$25.28 total to pay =$2117.15 paid =$1200 balance $917.15

month 3 starting amount =$917.15 interest =$11.08 total to pay =$928.23 paid =$928.23 balance =$0 total to pay 1200+1200+928.23 = $3328.23 it will take 3 months to pay a total of $3328.23
