Incorrect. The amount of water drained can be represented by $\displaystyle\frac{{1}}{{2}}{x}\usepackage{cmbright}\Huge\$ . If $\displaystyle\frac{{1}}{{2}}\usepackage{cmbright}\Huge\$ gallons of water is drained every minute, then after 1 minute she will have lost $\displaystyle\frac{{1}}{{2}}\cdot{1}=\frac{{1}}{{2}}\usepackage{cmbright}\Huge\$ gallon. After 2 minutes she will have lost $\displaystyle\frac{{1}}{{2}}\cdot{2}={1}\usepackage{cmbright}\Huge\$ gallon, and after 3 minutes she will have lost $\displaystyle\frac{{1}}{{2}}\cdot{3}={1}\frac{{1}}{{2}}\usepackage{cmbright}\Huge\$ gallons. Can you use this pattern to solve the problem?
