Answer: Scroll Down Below...Explanation - To decide the long-run cost function of bearing all-American baseballs, we need to believe the costs guide labor (L), conveyance (K), and different fabrics (M) established the likely facts.Given:- Cost of each part of labor (L): $1 in Costa Rica and $2 in Georgia.- Cost of each whole of conveyance (K): $4 from Costa Rica and $2 from Georgia.- Cost of a part of all added matters linked (M): $3.We are likewise likely that bearing each whole of gain demands 4 parts of labor, 1 part of conveyance, and 2 wholes of all different matters linked.To reckon the long-run cost function, we need to decide the costs guide the quantities of labor (L), conveyance (K), and matters (M) necessary to produce a likely portion of yield (q).The cost function (c(q)) maybe signified in this manner:c(q) = (cost of labor for one) * (parts of labor) + (cost of conveyance for one) * (parts of conveyance) + (cost of matters apiece) * (wholes of matters)Substituting the likely costs and quantities into the cost function, we take:c(q) = (1 * L/4 + 2 * K + 3 * M/2)Simplifying the verbalization, we have:c(q) = (L/4 + 2K + 3M/2)Therefore, the long-run cost function of bearing all-American baseballs is best detailed by:c(q) = (L/4 + 2K + 3M/2)Among the alternatives determined, the tightest likeness of the long-run cost function is:c(q) = (L/4 + 2K + 3M/2)
