4. Insert formulas in cells E7, F7, and G7 to calculate the total number of ads in the campaign, the total gross impressions, and the total cost for the radio campaign. 5. Insert formulas in cells H4:H6 to calculate the percentage of ads placed on each network. b. Create a constraints table that identifies the constraints that you must use in your solution. After determining the objective cell, the variable cells, and the constraints, use the Solver Parameters dialog box to specify your inputs. 7. Use Solver to calculate your solution and then evaluate your solution. If necessary, add, change, or delete constraints and rerun Solver to produce a feasible solution. Balance the need to stay at or under the budget with the desire to reach a level of at least 15,000,000 gross impressions. 8. Produce an answer report for your solution
