Answer
$190 commission
Work Step by Step
Create a proportion using ratios of commission:sale.
$\frac{\$75\ commission}{\$300\ sale}=\frac{\$x\ commission}{\$760\ sale}$
Set the product of the means equal to the product of the extremes and solve for the variable.
$300\times x=75\times 760$
$300x=57000$
$300x\div300=57000\div300$
$x=190$
