Consider the following information for a simultaneous move game: If you advertise and your rival advertises, you each will earn 12 million in profits.If neither of you advertise, you will each earn 15 million in profits. However, if one of you advertises and the other does not, the firm that advertises will earn 20 million and the non-advertising firm will earn 5 million.If you and your rival plan to be in business for only one year, the Nash equilibrium is

a. For each firm to advertise

b. for neither firm to advertise

c. for your firm to advertise and the other not to advertise

d. for the other firm to advertise and your firm not to advertise

Please provide a calculation.
