Howt is total utility maximized in Economics?

The marginal utility of good A is 4 utils and its price is $2.The marginal utility of good B is 6 utils and its price is $1. Is the individual consumer maximizing total utility if she spends a total of $3 by buying one unit of each good? If not, how can more utility be obtained?

Alyssa enjoys eating ice cream cones. The following table contains information on Alyssa's utility from ice cream each week.

Fill in the two missing cells of the table.

On the following graph, use the purple points (diamonds symbol) to plot Alyssa's total utility (TU) curve if she consumes zero, one, two, three, four, five, or six cones of ice cream per week.

Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.

On the following graph, use the blue points (circle symbol) to plot Alyssa's marginal utility (MU) curve from consuming her first six cones of ice cream.

For Alyssa, increasing her consumption of ice cream results in marginal utility.

When deciding consumption levels of more than one good, the utility-maximizing rule states that you are maximizing utility when

the marginal utility o two goods are equal

the marginal utility of two goods are zero

the ratio of marginal utility to price of two goods is zero

the ratio of marginal utility to price for the two goods are equal

QUESTION 2

My brother says the law of diminishing marginal utility is nonsense because he is way happier after his sixth beer than after his first one. Pick the best response.

He has a point, maybe this is something behavioral economists should take a look at.

True, but marginal utility refers only to the utility gained (or lost) by drinking that last beer, not to his total utility

There are always exceptions, but in general this law will hold.

True, but the law of diminishing marginal utility is really just saying that eventually he will prefer a glass of wine to another beer.

QUESTION 3

Frank spends $75 on 10 magazines and 25 newspapers. The magazines cost $5 each and the newspapers cost $2.50 each. Suppose that his marginal utility from the final magazine is 10 utils while his marginal utility from the final newspaper is also 10 utils. According to the utility-maximizing rule, Frank should:

Reallocate spending from magazines to newspapers

Reallocate spending from newspapers to magazines

Be satisfied because he is already maximizing his total utility

None of the above

QUESTION 5

In economics, a product provides utility if it:

is useful

violates the law of demand

takes more and more resources to produce successive units of it

satisfies consumer wants

Which of the following is true of an indifference curve?

Along an indifference curve utility is fixed.

If a consumer is rational then indifference curves may cross.

Indifference curves further from the origin are associated with lower levels of utility than those that are closer to the origin.

Because they are indifference curves, microeconomics students should be indifferent towards them.
