1. Riaz has a limited income and consumes only Apple and Bread. His current consumption choice is 3 apples and 5 bread. The price of apple is $3 each, and the price of bread is $2.5 each. The last apple added 5 units to Sadid's utility, while the last bread added 7 units. Is Riaz making the utility-maximizing choice? Why or why not? Do you suggest any adjustment in Riaz's consumption bundle? Why or why not? Give reasons in support of your answer. State the condition for a consumer's utility maximizing choice and illustrate graphically.

Q. Bridget has a limited income and consumes only wine and cheese; her current consumption choice is four bottles of wine and 10 pounds of cheese. The price of wine is $10 per bottle and the price of cheese is $4 per pound. The last bottle of wine added 50 units to Bridget's utility, while the last pound of cheese added 40 units. a. Is Bridget making the utility-maximizing choice? Why or Why not? b. If not, what should she do instead? Why? Please provide the correct answer. Thank you!
Suppose utility can be measured by "utils" and that Jim buys both coffee and bagels. The price of coffee is $2 and the price of a bagel is $3. If Jim is currently consuming coffee and bagels such that the marginal utility from the last cup of coffee consumed was 6 utils and the marginal utility from the last bagel consumed was 12 utils, is Jim maximizing utility? Why or why not? If not, what should Jim do? Explain in detail.
Timothy is trying to achieve the optimum combination of bags of peanuts and bags of popcorn he should buy with his $20 budget. The price of peanuts is $5 per bag and the price of popcorn is $4 per bag. If Timothy’s marginal utility from consuming his last bag of peanuts is 20 utils and his marginal utility from consuming his last bag of popcorn is 12 utils, Timothy should? A. consume more bags of popcorn and less of peanuts. B. consume more bags of peanuts and less of popcorn. C. not change his consumption. He has already achieved the consumer optimum. D. consume fewer bags of peanuts and popcorn. E. consume more bags of popcorn and peanuts. Please type out the correct answer ASAP within 40 50 minutes, with proper explanation of the each option given. Will give upvote only for the correct answer.thank you.
Currently, Paula is maximizing utility by purchasing five TV dinners (T) and four LeanCuisine Meals (L) each week. Suppose both T and L cost $5 each.a. Graph Paula’s initial utility-maximizing choice.b. Suppose the price of T falls by $1 and the price of L rises by $1.25. Can Paula stillafford to buy her initial consumption choices? What do you know about her new budgetconstraint?c. Make a new graph to show why Paula will choose to consume more T and less Lgiven her new budget constraint to maximize utility. Is her utility increased, decreased,or unchanged given the price change? [Hint: try to make the graph as big as possible tosee how the utility is tangent/intersects with the lines more easily] d. In part (b), suppose another scenario where the price of T rises by $1 and the priceof L falls by $1.25. Is Paula’s utility increased, decreased, or unchanged given the pricechange?
How can one's choice of purchases/consumption be infuenced by utility or marginal utility?
Ray buys only hamburgers and bottles of root beer out of a weekly income of $100. He currently consumes 20 bottles of root beer per week, and his marginal utility of root beer is 6. The price of root beer is $2 per bottle. Currently, he also consumes 15 hamburgers per week, and his marginal utility of a hamburger is 8. Is Ray maximizing utility at his current consumption basket? If not, should he buy more hamburgers each week, or fewer?
Larry and Teri allocate their consumption between two goods: hats and bats. The price of hats is €5 each, and the price of bats is €10 each. For Larry, the marginal utility of the last hat consumed was 8, and the marginal utility of the last bat was 24. For Teri, the marginal utility of the last hat was 6, and the marginal utility of the last bat was 12. Which consumer is not maximizing his/her utility? How can you tell? How should he/she change their allocation?
1. A consumer has an income of $3024 to spend each day. The only two goods the consumer is interested in purchasing are goods A and B. The marginal-utility schedules for these two goods are shown in the table below. The price of B does not change and is $378. The marginal utility per dollar from B is also shown in the table. But the price of A varies as shown in the table. The marginal utility per dollar from A when the price of A is $1512 and $756 is shown in the following table. Good A Good B Quantity MU MU/$1512 MU/$756 MU MU/$378 1 24 2 15 3 12 4 8 5 6 6 4 48 32 24 16 8 4 ||||| ||||| |||
EXERCISE 3 If Joe decides to allocate his entire weekly allowance between energy drinks and coffee, he could afford 9 energy drinks and 3 cups of coffee, or 6 cups of coffee and 2 energy drinks. Suppose a cup of coffee costs £2.80. Calculate the price of an energy drink and Joe’s weekly allowance. Write down Joe’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 Joe’s budget set would change if his allowance was reduced by £5.20 a week. Show the relevant changes graphically. How should the price of coffee change so that Joe could still afford to buy 6 cups of coffee and 2 energy drinks? Discuss how Joe’s budget constraint would change if the government subsidised consumption of coffee by £0.50 per cup of coffee.
3. Sam has set aside $480 for entertainment this month, which is golf (x) and/or bowling (z). A round of golf is $40 and a night of bowling is $30. His utility function is U = 3x + 2z. What is his MRS? a. b. c. Solve for the optimal choice of golf and bowling. Draw a graph of the budget line (including intercepts), a few indifference curves, and the optimal choice for Sam.
Assume Pat spends all of her allowance to purchase 4 apples and 4 candy bars. Pat's marginal utility of the fourth apple is 20 utils, and her marginal utility of the fourth candy bar is 40 utils.
