1. Go to the Suppliers worksheet, where Benicio wants to determine whether subcontracting could reduce the cost of the new virtual assistant product. Run Solver to solve this problem. Set the objective as minimizing the total cost, and use the units produced values as the changing variable cells. Adjust the number of units produced by each supplier using the following constraints:
   1. Set the total number of virtual assistants produced as greater than or equal to 11,000, DIG Technology's minimum production goal.
   2. Set the total cost to be less than or equal to 925,000, the maximum total cost DIG Technology wants to spend.
   3. Set the number of virtual assistant units produced by each supplier to be less than or equal to 4000 to balance the production among the suppliers. Also, make sure that this same range contains integers since DIG Technology cannot sell a fraction of a product.
   4. Run Solver, keep the solution, and then return to the Solver Parameters dialog box. Save the model in the range A14:A21.
