Can somebody put this question into excel sheets?

Suppose that Penny Chairs has three media options: radio, TV$,$ and ads in Furniture World $($an industry publication$).$ The table below provides information related to the costs, exposure values $($i$.$e$.$ how many people see the ad and is typically derived from market research studies$),$ and limitations on the allowable number of ads in each medium desired by the firm. The company would like to achieve a total

exposure value of at least $60,000.$

Cost$/$Ad Exposure:

Radio: $$500$

TV: $$2000$

Furniture World: $$200$

Exposure Value$/$Ad:

Radio: $$2000$

TV: $$4000$

Furniture World: $$2700$

Minimum Units:

Radio: $0$

TV: $10$

Furniture World: $6$

Maximum Units:

Radio: $15$

TV: No Limit

Furniture World: $12$

a$)$ What advertising mix should be implemented in order to minimize the cost of achieving the minimum required total exposure. Which constraints are binding? Why?

b$)$ Furniture World has instituted a policy where advertisers must run a minimum of $8$ ads and has raised the cost per ad to $$215.$ How will this change the mix of ads that Penny Chairs runs?
