It is given in the question that
Sam sells cars and earns 3.5% commission in sales. In one day he sold 3 of the same cars each for $21,500.
Selling price of each car is $ 21,500. Therefore selling price of 3 cars is
[tex]3*21500= $64500[/tex]
And Sam earns 3.5 % commission .
So to find the Sam's commission, we have to do
[tex]=0.035*64500=$2257.50[/tex]
And the Sam's earning is $2257.50 .
