Last week Sara’s income was $12 a week. The price of popcorn was $3 a bag, and the price of a smoothie was $3.e. Draw a graph of Sara’s budget line with the quantity of smoothies on the x-axis.f. What is the slope of Sara’s budget line? What determines its value?
This week Sara’s income falls from $12 to $9 a week, while the price of popcorn isunchanged at $3 a bag and the price of a smoothie is unchanged at $3.h. What is the effect of the fall in Sara’s income on the relative price of a smoothiein terms of popcorn? What is the slope of Sara’s new budget line if it is drawnwith smoothies on the x-axis?
Jerry spends his entire budget on bread and gasoline. His preferences are complete, transitive,
monotonic, and convex. For Jerry, bread is an inferior good that follows the law of demand.
Moreover, his cross-price elasticity of demand for gasoline with respect to the price of bread is
negative. Suppose the price of bread increases, all else constant.
a. Create a chart to show the total, income, and substitution effects on bread and gasoline of the
increase in the price of bread.
b. Use budget lines and indifference curves to graphically illustrate the three effects. Be sure to
label each effect on your graph (or through the chart from part a) and plot bread on the x-axis
and gasoline on the y-axis
