Problem: Alice has utility from hours of TV and hours of movies given by U (t, m) = 5t + 4m.
(a) Obtain the equation of the indifference curve for the utility level U = 100 (set m in the vertical axis).
(b) Draw three indifference curves for Alice, and label the levels of utility that they correspond to (you can choose the utility levels that you want). Set m in the vertical axis and t in the horizontal axis.
