Profit is the difference between revenue and cost. The
revenue, in dollars, of a company that manufactures
televisions can be modeled by the polynomial 3x2 + 180x.
The cost in dollars, of producing the televisions can be
modeled by 3x2 – 160x + 300. The variable x is the number
of televisions sold.
if 150 televisions are sold what is the profit?
