This cannot be the answer because it is greater than the total number of cars. It is the solution to $\displaystyle\frac{{3}}{{10}}=\frac{{330}}{{n}}\usepackage{cmbright}\Huge\$ . Each ratio should compare things in the same order, such as SUVs to cars. The correct proportion would have been $\displaystyle\frac{{3}}{{10}}=\frac{{n}}{{330}}\usepackage{cmbright}\Huge\$ . The answer is 99 SUVs.
