Suppose the daily supply equation for noise cancelling wireless headphones is given by p = S(x) = 20 + 90-0.09x where p is in dollars and x is the number of headphones produced daily. Determine the quantity supplied if the market price is 290 dollars. In (3) Quantity supplied (exact value) = units 0.09 Determine the producer surplus at the market price of 290 dollars. Producer surplus (exact value) = dollars Producer surplus ( rounded to the nearest dollar) = dollars
