Answer :
To determine the comission we use a rule of three:
[tex]\begin{gathered} 250200\rightarrow100 \\ x\rightarrow1.2 \end{gathered}[/tex]By the rule of three we have to do the cross multiplication; this means that we need to multiply 1.2 by 250200 and then we divide the result by 100, this can be express as:
[tex]\begin{gathered} x=\frac{(1.2)(250200)}{100} \\ =\frac{300240}{100} \\ =3002.4 \end{gathered}[/tex]Therefore the comission is $3002.4
