1. Go to the Premiums worksheet, which lists data about premiums Flamingo Guitars occasionally offers to include an accessory along with the sale of three types of deluxe guitars. The company wants to keep the total costs low when running the premium offers. Isabella wants to know how many premiums to offer of each type to minimize costs while running up to five premiums a year. Use Solver to find this information as follows:
   1. Use the total cost of the premiums (cell E9, named Total_cost) as the objective cell in the Solver model, with the goal of minimizing the value.
   2. Use the number of premiums offered (range B7:D7) as the changing variable cells.
   3. Determine and enter the constraints based on the information provided in Table 2.
   4. Use Simplex LP as the solving method to find a global optimal solution.
   5. Solve the model, keeping the Solver solution.
