(a)
Draw the budget constraint when income = $4,000; PX = $50; PY = $100.
(a)
Explanation of Solution
Since the income is $4,000 and price of good X is $50, the quantity of good X can be calculated as follows:
Thus, the consumer will consume 80X.
Since the income is $4,000 and price of good Y is $100, the quantity of good Y can be calculated as follows:
Thus, the consumer will consume 40Y.
Now, the budget constraint can be represented as follows:
In Figure 1, the vertical axis measures the quantity of good Y and the horizontal axis measures the quantity of good X.
(b)
Draw the budget constraint when income = $3,000; PX = $25; PY = $200.
(b)
Explanation of Solution
Since the income is $3,000 and price of good X is $25, the quantity of good X can be calculated as follows:
Thus, the consumer will consume 120X.
Since the income is $3,000 and price of good Y is $200, the quantity of good Y can be calculated as follows:
Thus, the consumer will consume 15Y.
Now, the budget constraint can be represented as follows:
In Figure 2, the vertical axis measures the quantity of good Y and the horizontal axis measures the quantity of good X.
(c)
Draw the budget constraint when income = $2,000; PX = $40; PY = $150.
(c)
Explanation of Solution
Since the income is $2,000 and price of good X is $40, the quantity of good X can be calculated as follows:
Thus, the consumer will consume 50X.
Since the income is $2,000 and price of good Y is $150, the quantity of good Y can be calculated as follows:
Thus, the consumer will consume 13.33Y.
Now, the budget constraint can be represented as follows:
In Figure 3, the vertical axis measures the quantity of good Y and the horizontal axis measures the quantity of good X.

- Question 4 Given the following budget line ???+???=? And that the slope of the budget line depends only on relative prices, show what happens to the budget line when: (a) ?? rises (b) ? reduces (c) Both ?? and ?? rise by the same proportion (d) a consumer is given an in-kind transfer of 40 units of good ?

Having made these decisions, Anthony has a remaining budget of $15 a week, which he spends on two goods: coffee and magazines. The price of a cup of coffee is $2.50 and the price of a magazine is $5. 1. Construct a table showing the alternative combinations of the two goods that Anthony might purchase in a given week. 2. Use the data in your table to graph Anthony’s budget line. 3. What is the opportunity cost of each cup of coffee? What is the opportunity cost of each magazine? 4. Based on this information, do we know how many cups of coffee or magazines Anthony should buy each week? Why or why not? 5. Anthony decides he wants to upgrades to the $5 cup of coffee- the larger cup with extra flavoring! Using a graph, show how this will change Anthony’s budget line.

She has decided to serve sushi and yakitori meat skewers. Each serving of sushi is $8 and each yakitori skewer is $2. Kimiko has $240 to spend on the party. Please graph her budget line. Her friend, Barry, thinks there will not be enough food, so he gives Kimiko $80 more to spend on the party (she now has $320). How will this affect the budget line? a. There will be a parallel shift of the budget line away from the origin. b. There will be a parallel shift of the budget line towards the origin. c. There will be an outward shift of point A only. d. There will be an outward shift of point B only.arrow_forward
