A contractor is considering hiring ONE new employee, either a painter or a carpenter, to help complete a large scale project. The cost (in dollars) of the project is given by C(x, y) = 542 ln(xy²) - 14xy + 327x+201² + 4000 where x represents the number of painters and y represents the number of carpenters working on the project. Use marginal cost to determine which of the following options is the MOST cost effective if 5 painters and 14 carpenters are currently employed. a) It is NOT cost effective for the contractor to hire at this time. b) The contractor should hire one more carpenter. c) d) The contractor should hire one more painter.
