- Suppose Lorenzo has a weekly budget of $48 to spend on ranch dressing and peanut butter. Ranch dressing is priced at $4 per bottle, and peanut butter is priced at $6 per jar. If Lorenzo spends his entire $48 on ranch dressing, he can buy jars of peanut butter. buy Use the blue line (circle symbol) to plot Lorenzo's budget constraint on the following graph. Next, use the orange point (square symbol) to shade the area that represents combinations of ranch dressing and peanut butter that are affordable for Lorenzo. Finally, place the black point (plus symbol) on the point on Lorenzo's budget constraint that corresponds to a scenario in which Lorenzo spends $24 on each good.

Normal and inferior goods Megan likes going to the ballpark to watch baseball, and she also is fond of going to the theater to listen to the symphony orchestra. The following diagram shows two of Megan's indifference curves for going to ballgames and symphonies. With Megan's initial budget constraint (BC), she chose to go to five symphonies and three baseball games per month (point X). Then her budget constraint shifted to BC, and she chose to go to four symphonies and six ballgames per month (point Y), SEOTING 2 4 SYMPHONIES BCarrow_forwardBy definition, a budget constraint shows the consumption bundles that a consumer can afford. Assume that a college student spends her income on Mc-cheese and CD's. The price of one box of Mc-cheese is $1.00 and the price of one CD is $10.0 . If she has $90 of income, she could choose to consume : a- 10 boxes and 9 CDs b- 30 boxes and 7 CDs c- 25 boxes and 6 CDs d- 25 boxes and 8CDSarrow_forward
