Sunseri Tech sells $2$ products, Speakers and TV$\text{'}$s$.$ The speakers have a per unit contribution margin of $$6$ and

requires $0\mathrm{.}4$ machine hours to assemble. The TV$\text{'}$s have a per unit contribution margin of $$8$ and require $0\mathrm{.}6$

machine hours to assemble. I Sunseri only has $65,000$ machine hours that be dedicated to production, then

what will the total contribution margin be if they choose to only make the most profitable product?
