Solve the problem.Suppose that the number of VCR's manufactured at a factory is given by 
where t is the number of hours that the factory has been in operation. Suppose that the cost, in dollars, of producing n units is given by 
. Find and interpret 
A. (C?N)(t) = 233 + 245t; This function gives the cost as a function of the number of hours that the factory is in operation. B.
