Owen saw that the price of peaches had gone down, and
so he decided to buy more peaches. Based on this
information only, what does Owen's reaction reflect?
Choose 1 answer: A Owen's demand for peaches has
increased. B Owen's quantity demanded for peaches has
increased. Owen has experienced an increase in income.
Owen observed that there has been an increase in the
price of other fruit, a substitute for peaches. Owen expects
future price changes.

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-axisarrow_forward
