ACCA F2的一道预算题目
Unemployment numbers actually recorded in a town for the second quarter of the year 2000 were 4700.The underlying trend at this point was 4300 people and the seasonal factor is 0.92.Using the multiplicative model for seasonal adjustment,what is the seasonally-adjusted figure(in whole numbers) for the quarter?A 3932 B3956 C5068 D5109

选B 0.92*4300
按照乘法模型进行预测时,实际数据是无关数据,重要的是seasonal adjustment预测基数.但是答案给的是D 4700/0.92=5109(to the nearest whole number) 你能解释详细一点么
