If Salesman A had one sale he would earn $1,365 because he makes $65 dollars per sale plus a weekly commission of $1,300. Salesman B would make $340 because he makes $300 dollars weekly and $40 per sale. Salesman C would make $900 dollars, because he makes no commission and gets only weekly pay. Altogether, they would make $2,605.
The straight lines equal 180 and you subtract 180 to 150 and 180 to 100 to get 30 and 80 and the inside of a triangle is 180 and you subtract 30 and 80 to 180 to get 70.
