Incorrect. From the description, Hayden $\displaystyle{\left({h}\right)}\usepackage{cmbright}\Huge\$ is at least $\displaystyle{\left(\ge\right)}\usepackage{cmbright}\Huge\$ twice as old (2) as Colin $\displaystyle{\left({c}\right)}\usepackage{cmbright}\Huge\$ . Check values for Hayden's and Colin's ages in your inequality and make sure that they work.
