Incorrect. The pool already has 20 gallons of water, so the amount of water in the pool at any time can be represented by $\displaystyle{2}{x}+{20}\usepackage{cmbright}\Huge\$ , where x is the number of minutes. How many minutes will it take for the 50 gallon pool to be full, or for $\displaystyle{2}{x}+{20}={50}\usepackage{cmbright}\Huge\$ ?
