You are a COMMISSION ONLY salesperson for a manufacturers agent.

You sell three types of floor cleaners. Self$-$driving sweepers sell for $$34,000.$ Riding sweepers sell for $$16,000.$ Push sweepers sell for $$5,000.$

The manufacturing cost $($cost of goods sold$)$ for the self$-$driving sweeper is $$17,000.$ The manufacturing cost $($cost of goods sold$)$ for the riding sweeper is $$6,000.$ The manufacturing cost $($cost of goods sold$)$ for the push sweeper is $$2,100.$

You receive a $10\%$ commission on the GROSS MARGIN $($sales price $-$ COGS$).$ In other words, you need to calculate the gross margin for each item in order to calculate your commission.

What is your monthly commission if you sell $3$ self$-$driving sweepers, $6$ riding sweepers, and $8$ push sweepers this month? $($You do not need to put a $ in your answer$)$
