A
Marv Pilson has $50 worth of groceries in a shopping cart at his local Shop 'n Save. Assume that the marginal utility per dollar of the liter bottles of soft drink in Marv's cart equals 50. The marginal utility per dollar of the boxes of cereal in Marv's cart equals 20. Marv has only $50 to spend, but has not yet paid for his groceries. How can Marv increase his total utility without spending more than $50? A) Marv should buy fewer boxes of cereal and more bottles of soft drink. B) Marv should buy more boxes of cereal and fewer bottles of soft drink. C) Marv should substitute his favorite soft drink or the cereal in his cart for generic brands that have lower prices. D) Marv should buy fewer boxes of cereal and fewer bottles of soft drink. He can then spend more on other items.
A
Optimal decisions are made A) at the margin. B) if information about prices and marginal utilities is known. C) in the marketplace. D) when marginal utility is minimized.
A
Terence has $50 per week to spend on Subway sandwiches and milkshakes. The price of a Subway sandwich is $5 and the price of a milkshake is $4. He buys 6 sandwiches and 5 milkshakes.
