Exhibit 7-3
A company has the following historical data on the number of ad exposures and the corresponding number of units sold of one of its products:
$$\begin{array}{l}\text { Historical }\\\begin{array} { | c | c | } \hline \text { Ads } & \text { Units } \\\hline 0 & 3 \\\hline 20 & 18 \\\hline 40 & 34 \\\hline 60 & 46 \\\hline 80 & 56 \\\hline 100 & 65 \\\hline 120 & 72 \\\hline 140 & 78 \\\hline 160 & 82 \\\hline 180 & 85 \\\hline 200 & 90 \\\hline 220 & 90 \\\hline 240 & 93 \\\hline 260 & 94 \\\hline 280 & 95 \\\hline 300 & 101 \\\hline 320 & 98 \\\hline 340 & 100 \\\hline 360 & 98 \\\hline 380 & 101 \\\hline 400 & 105 \\\hline\end{array}\end{array}$$
-[Part 2] Refer to Exhibit 7-3.Formulate a nonlinear optimization model to find the parameters of a function of the form: f(x)= a(1 − e−bx)to model demand for its product as a function of ad exposures (x).In terms of fit,is this model better or worse than the model in Part 1
