question 68

Short Answer

Solve the problem using your calculator.
-The paired data below consist of the costs of advertising (in thousands of dollars)and the number of products sold (in thousands). Use a graphing calculator to model the data with a linear function that predicts the number of products sold as a function of the cost of advertising.
$\begin{array} { c | r r r r r r r r } \text { Cost } & 9 & 2 & 3 & 4 & 2 & 5 & 9 & 10 \\\hline \text { Number } & 85 & 52 & 55 & 68 & 67 & 86 & 83 & 73\end{array}$
A) y=-26.4-1.42 x
B) y=26.4+1.42 x
C) y=55.8-2.79 x
D) y=55.8+2.79 x
