S = 100 (11,000 x 1200)/17,500 = 75,429 c. we would get time series data on s, y, z, p, and use regression to estimate k d. sales in t may have unknown variables because of unknowns before t. We first need to estimate Yt, Zt, and Pt before we can estimate St. 2. a. St + 1 = 100,000 (1 + .08) 1 = 108,000 St + 2 = 100,000 (1 +.08) 2 = 116,640 St + 3 = 100,000 (1+.08)3 = 125,971 b.
