1. What would Thabo's indifference curves look like if he cared just as much about Lebo's consumption as his own?2. What would they look like if he derived utility only from the total of his and Lebo's consumption3. What would they look like if he derived utility only from Lebo's consumption?I don't know how many of those questions you are allowed to answer, but I'm very stuck on these questions and would like see how to them, thank you :)

Thabo picks a R100 note while walking with his friend Lebo. Thabo can keep the R100 note or share it with Lebo, depending on his social preferences. The diagram below shows Thabo's indifference curves if he is selfish and if he is somewhat altruistic. Your task is to draw three more social indifference curves. Each social indifference curve should be on its own graph. The intercept and the slope of the zero-sum-game remain the same. Answer the following questions: Lebo's payoff Thabo's indifference 4 curves if he is selish Thabo's indifference curves if he is somewhat altruistic R100 Thabo's payoff
