Think about the budget line given by 12X + 15Y = 360. Draw this budget line. How will the budget line move if the government now imposes 10% sales tax on both commodities? Draw the new budget line with taxes imposed. How will the budget line move if the government decided to impose a 10% income tax instead of a sales tax? Which policy (10% sales tax and no income tax vs. 10% income tax and no sales tax) leaves the consumer with more purchasing power? (A graphical argument is sufficient.)
