Suppose that the total cost (in dollars) of producing a product is C(x, y) = 15 + 6x2 + 6y2, where x is the cost per pound for material and y is the cost per hour for labor. (a) If material costs are held constant, at what rate will the total cost increase for each $1-per-hour increase in labor? (b) If the labor costs are held constant, at what rate will the total cost increase for each increase of $1 in material cost?

Question
**Understanding the Impact of Material and Labor Costs on Total Production Cost** Suppose that the total cost (in dollars) of producing a product is given by the function \( C(x, y) = 15 + 6x^2 + 6y^2 \), where \( x \) is the cost per pound for material and \( y \) is the cost per hour for labor. **(a) Rate of Increase in Total Cost with Respect to Labor Costs** If the material costs are held constant, we need to determine the rate at which the total cost increases for each $1-per-hour increase in labor costs. You are encouraged to find this rate of increase. **(b) Rate of Increase in Total Cost with Respect to Material Costs** If the labor costs are held constant, we need to determine the rate at which the total cost increases for each $1 increase in material costs. You are encouraged to find this rate of increase.
