You may have chosen this answer because the compound inequality uses the word and, and you are familiar with an and statement being written in this way. The two inequalities simplify to $\displaystyle{j}\le{6}\usepackage{cmbright}\Huge\$ and $\displaystyle{j}>{10}\usepackage{cmbright}\Huge\$ . Since the graphs of $\displaystyle{j}\le{6}\usepackage{cmbright}\Huge\$ and $\displaystyle{j}>{10}\usepackage{cmbright}\Huge\$ have no overlap, the correct answer is: There is no solution.
