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)=1143ln(x^2y)−14yx−271x+12y^2+300 0

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 6 painters and 10 carpenters are currently employed.
