If a household has an income of $50 and buys only milk at $3 each unit and honey at $6 each unit, what is the household’s budget equation? Explain your answer.
Brenda wants to buy new car and has a budget of $25,000. She has just found a
magazine that assigns each car an index for styling and an index for gas mileage.
Each index runs from 1 to 10, with 10 representing either the most styling or best
gas mileage. While looking at the list of cars, Brenda observes that on average, as
the style index increases by one unit, the price of the car increases by $6,250. She
also observed that as the gas-mileage index rises by one unit, the price of the car
increases by $5,000.
Illustrate the various combinations of style (S) and gas mileage (G) that Brenda
could select with her $25,000 budget.
Using the line drawing tool, illustrate Brenda's budget line. Label this line 'Budget
Line'.
Carefully follow the instructions above, and only draw the required object.
Suppose Brenda's preferences are such that she always receives two times as
much satisfaction from an extra unit of styling as she does from gas mileage. What
type of car will Brenda choose?…
Suppose John decides to buy 4 units of food and 4 units of clothing with his $12 budget. Would his marginal utility per dollar spent on food be greater than or less than his marginal utility per dollar spent on clothing? What does this tell you about how he should substitute food for clothing if he wanted to increase his utility without spending any more money?

- With the help of a graph, explain how the decrease in the income affect the consumer's choice for normal goods?arrow_forwardA consumer is currently purchasing three pairs of jeans and five T-shirts per year. The price of jeans is $60, and shirts cost $10. At the current rate of consumption, the marginal utility of jeans is 240, and the marginal utility of shirts is 30. Based on the model of consumer choice, what should this consumer do to maximize utility? Purchase fewer shirts and more jeans. Purchase more shirts and fewer jeans. Purchase only jeans. This consumer is already maximizing utility. Purchase only shirts.arrow_forwardPam has a monthly budget of £120 to be spent on T-shirts and trainers. She could afford to buy two T-shirts and two pairs of trainers. She could also buy eight T-shirts. In each case, she would be spending her entire monthly allowance. Calculate the price of a T-shirt and the price of a pair of trainers. Write down Pam’s budget equation and draw the corresponding budget line. Mark the two consumption bundles mentioned above. In your graph, clearly label the axes, the budget line, and calculate the coordinates of the points of intersection of the budget line with each axis. Interpret each of those points. Discuss how Pam’s budget set would change if the price of a T-shirt doubles. Show the relevant changes graphically. How should Pam’s income change so that she could still afford to buy two T-shirts and two pairs of trainers? Discuss how Pam’s budget constraint would change if the government imposed a tax of £3 per each pair of trainers.arrow_forward
