Suppose the Cobb-Douglas production function for an automobile manufacturer isf(x, y) = 100x^0.6 + y^0.4,where x is the number of units of labor and y is the number of units of capital. Estimate the average production level if the number of units of labor x varies between 175 and 250 and the number of units of capital y varies between 375 and 450. Round your answer to two decimal places, if necessary
