Answer

(Answer may vary.) $\$308000$

Work Step by Step

Answer may vary. From Exercise (2), the equation we found was $y=\frac{1}{5}x+241$. Substitute $335$ (since $x$ is in thousand dollars) to $x$ to obtain: $\begin{align*} y&=\frac{1}{5}(335)+241\\ y&=67+241\\ y&=308 \end{align*}$ Thus, the selling price is $\$308,000$.
