Correct. Because revenue is found by multiplying price by demand ( $\displaystyle{R}={p}\cdot{d}\usepackage{cmbright}\Huge\$ ), demand can be found by dividing revenue by price. ( $\displaystyle{d}=\frac{{R}}{{p}}\usepackage{cmbright}\Huge\$ ). Dividing the equation $\displaystyle-{0.25}{{p}}^{{2}}+{250}{p}\usepackage{cmbright}\Huge\$ by p results in the equation $\displaystyle-{0.25}{p}+{250}\usepackage{cmbright}\Huge\$ .
