You correctly found the difference of the absolute values. However, you have to compare $\displaystyle{\left|-{35.47}\right|}\usepackage{cmbright}\Huge\$ and $\displaystyle{\left|{48.082}\right|}\usepackage{cmbright}\Huge\$ . If the negative number has a greater absolute value, the answer is negative. If the positive number has a greater absolute value, the answer is positive.
