The average cost function, AC for a commodity is given by AC = `x + 5 + 36/x` in terms of output x. Find
1) The total cost, C and marginal cost, MC as a function of x.
2) The outputs for which AC increases
The price of relatives and weights of a set of commodities are given below:
|Weights||x||2x||y||y + 3|
If the sum of the weights is 40 and the weighted average of price relatives index number is 122, find the numerical values of x and y.
