Question 3. Consider a situation in which two individuals are involved in a Synergistic relationship. Suppose that the players choose their eifort levels sequentially. rather than simultaneously. First individual 1 chooses an effort level :11, then individual 2 chooses an effort level o2. An effort level is a nonnegative number, and individual i 's preferences (for ii = 11 2} are represented by the payoff function oiilc + ej- oi), where j is the other individual and c :r 0 is a constant. Find the subgame perfect equilibrium of this game
