8. unit versus marginal cost Return to Example 7.3 and focus on the constant returns to scale case of α = β = .5. Determine total cost, marginal cost of each product, unit cost of each product under the impressionism school, and unit cost of each product under the modernism school for each of the following output pairs: q = [3, 8], q = [8, 3] and q = [10, 10].

Also determine the corresponding percentage estimation errors.
