Mr.Ziegler earns $2000 for every used car he sells and $4000 for every new car he sells. How much would he make if he sold ''r'' used cars and ''s'' new cars?
To calculate Mr. Ziegler's total sales, you may use the equation 2000(r) + 4000(s) = total sales, where "r" means used cars & "s" for new cars.
