It is often said that the economy of Arizona depends on the “Five C’s”: Copper, Cattle, Cotton, Citrus, andClimate. Assume a (highly simplified) model of the Arizona Economy that depends only on C1, C2, C3, C4,and C5, which represent the number of economic units (pennies, pounds, etc) purchased of each of the FiveC’s, respectively. Further assume that the Utility, or Economic Value (which is different from DollarValue), can be described by the function:U(C1, C2, C3, C4, C5) = C1∙C2∙C3∙C4∙C5As a mathematical function, does U have a maximum or minimum value? What values of Ci correspond tothe minimum value of U? What values of Ci correspond to the maximum value of U? Do these values of Cimake sense from an economic standpoint?
