Correct. 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\$ . This implies that $\displaystyle{h}\ge{2}{c}\usepackage{cmbright}\Huge\$ or $\displaystyle{2}{c}\le{h}\usepackage{cmbright}\Huge\$ .
