Sales in four consecutive months are 100, 200, 250 and 300 units respectively. In these same four months, the corresponding f beginning of the months were 80, 220, 170 and 180 units respectively. What is the accuracy of the forecast over the 4-month p measure? (Assume % is based on the sales) a. 60 units
b. 28%
c. 37%
d. none of the above

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
