Multiple Choice

Write the best-fit linear model for the data.
-The paired data below consist of the costs of advertising (in thousands of dollars) and the number of products sold (in thousands) . The linear model for this data is $\mathrm { y } = 55.8 + 2.79 \mathrm { x }$ , where $\mathrm { x }$ is the cost of advertising (in thousands of dollars) and $y$ is number of products sold (in thousands) . Use this model to predict the number of products sold (in thousands) if the cost of advertising is $\$ 8000$ .
$$\begin{array} { c | r r r r r r r r } \text { Cost } & 9 & 2 & 3 & 4 & 2 & 5 & 9 & 10 \\\hline \text { Number } & 85 & 52 & 55 & 68 & 67 & 86 & 83 & 73\end{array}$$
