Solve the problem.A large oil company produces three grades of gasoline: regular, unleaded, and super-unleaded. To produce these gasolines, equipment is used which requires as input certain amounts of each of the three grades of gasoline. To produce a dollar's worth of regular requires inputs of $0.14 worth of regular, $0.18 worth of unleaded, and $0.17 worth of super-unleaded. To produce a dollar's worth of unleaded requires inputs of $0.14 worth of regular, $0.15 worth of unleaded, and $0.13 worth of super-unleaded. To produce a dollar's worth of super-unleaded requires inputs of $0.15 worth of regular, $0.17 worth of unleaded, and $0.11 worth of super-unleaded. In addition, the oil company has final demands for each of the different grades of gasoline. Find the technology matrix that
would be used in determining the total output of each grade of gasoline. What will be an ideal response?
