You did not line up the decimals when finding the difference of the absolute values. First subtract $\displaystyle{48.082}-{35.47}\usepackage{cmbright}\Huge\$ , lining up the decimal points. Then compare $\displaystyle{\left|-{35.47}\right|}\usepackage{cmbright}\Huge\$ and $\displaystyle{\left|{48.082}\right|}\usepackage{cmbright}\Huge\$ to see if the answer is positive or negative.
