According to sales data, a bookstore can sell an average of 25 exclusive novels daily, which costs $100 each. If the exclusive novel costs $125, the bookstore can sell a daily average of 20 units. Provide and sketch the graph of the linear demand function for the exclusive novel sales. Determine the prices at which the demand function is defined.

ANSWERS OPTIONS

Linear Demand Function: $d\left(p\right)=-\frac15p+45$ , Domain: $\left(0,225\right)$

Linear Demand Function: $d\left(p\right)=\frac15p+45$ , Domain: $\left(-225,0\right)$

Linear Demand Function: $d\left(p\right)=-5p+475$ , Domain: $\left(0,95\right)$

Linear Demand Function: $d\left(p\right)=5p+475$ , Domain: $\left(-95,0\right)$
