Jane consumes only 2 goods(good 1 and good 2). her budget line has an intercept of 40 for good 1, and an intercept of 80 for good2; p2=20. a) what is p1?

b) what is jane's income?

c) write an equation of jane's budget line and draw her budget line. ( hint; you need to substitute the income and prices in the budget line equation). could you show me step by step so I can learn how to do it? Thanks

a) Construct a table showing the alternative combinations of the two products that are available.

b) Plot the data in your table as a budget line in a graph. What is the slope of the budget line? What is the opportunity cost of one more candy bar? Of one bag of peanuts?

c) How, in general, would you decide which of the available combinations of candy bars and bags of peanuts to buy?

2) With current technology, suppose a firm is producing 750 screwdrivers daily. Also assume that the least-cost combination of resources in producing those screwdrivers is 15 units of labor, 20 units of land, 4 units of capital, and 3 unit of entrepreneurial ability, selling at prices of $50, $45, $75, and $50, respectively. If the firm can sell these 750 screwdrivers at $2.50 per unit,

4)Zeke likes to go to music concerts. The number of times per year that he attends concerts depends on both the price of the concerts as well as Zeke’s income and the cost of other types of entertainment—in particular, how much it costs to go see a movie instead of attending concerts. The three demand schedules in the $60,000 per year and movies cost $10 each. In scenario D2, Zeke's income is also $60,000 per year, but the price of seeing a movie rises to $12. And in scenario D3, Zeke's income goes up to $80,000 per year, while movies cost $12.

a)Using the data under D1 and D2, calculate the cross-elasticity of Zeke's demand for concerts at all three prices. (To do this, apply the midpoints approach to the cross-elasticity of demand.) Is the cross-elasticity the same at all three prices? Are movies and concerts substitute goods, complementary goods, or independent goods?

b)Using the data under D2 and D3, calculate the income elasticity of Zeke's demand for concerts at all three prices. (To do this, apply the midpoints approach to the income elasticity of demand.) Is the income elasticity the same at all three prices? Are concerts an inferior good?

PRICE D1 D2 D3
50 10 5 12
40 15 10 25
30 25 15 40

Income 60,000 60,000 80,000

Cost of revenue 10 12 12
