Hans made $252 for 18 hours
Thus, the rate at which Han's work is
[tex]\text{for 1 hour}\Rightarrow\frac{252}{18}[/tex]Hence, the amount he would make in 11 hours is
[tex]\begin{gathered} \text{ }\frac{\text{ \$252}}{18hr}\times11hr \\ =\frac{2772}{18} \\ =\text{ \$154} \end{gathered}[/tex]Therefore, Han will make $154 in 11 hours
