You are watching: When total utility reaches a maximum, then marginal utility is

FIGURE 21-1 Total and also marginal utility Curves TU and MU are graphed from the information in the table. (a) As more of a product is consumed, total energy boosts at a diminishing price, reaches a maximum, and also then declines. (b) Marginal utility, by definition, shows the alters in total utility. Hence marginal utility diminishes through boosted consumption, becomes zero when complete energy is at a maximum, and is negative when total energy declines. As shown by the shaded rectangles in (a) and also (b), marginal utility is the readjust in complete utility associated via each included hamburger. Or, alternatively, each new level of complete energy is discovered by adding marginal energy to the previous level of total energy.

Marginal utility:

A. is the added output a firm obtains once it adds an additional unit of labor.
B. describes why product supply curves are upsloping.
C. commonly rises as succeeding systems of a good are consumeD.
D. is the extra satisfaction from the usage of 1 even more unit of some excellent or business.

2. FIGURE 21-1 Total and marginal energy Curves TU and also MU are graphed from the information in the table. (a) As more of a product is consumed, full energy rises at a diminishing rate, reaches a maximum, and also then declines. (b) Marginal energy, by definition, mirrors the transforms in complete utility. Therefore marginal energy diminishes via raised usage, becomes zero once full utility is at a maximum, and also is negative as soon as full energy declines. As displayed by the shaded rectangles in (a) and also (b), marginal utility is the readjust in complete energy associated with each included hamburger. Or, alternatively, each new level of complete energy is found by adding marginal energy to the previous level of complete utility.
R-1 21-1

Marginal utility in Figure 21-1b is positive, yet declining, once complete energy in Figure 21-1a is positive and:

A. rising at an enhancing price.
B. falling at an enhancing rate.
C. rising at a decreasing price.
D. falling at a decreasing rate.

3. FIGURE 21-1 Total and also marginal energy Curves TU and MU are graphed from the information in the table. (a) As more of a product is consumed, total energy boosts at a diminishing price, reaches a maximum, and also then declines. (b) Marginal utility, by definition, mirrors the alters in total energy. Thus marginal utility diminishes with raised consumption, becomes zero when complete utility is at a maximum, and is negative as soon as full utility declines. As displayed by the shaded rectangles in (a) and also (b), marginal utility is the change in full energy associated through each included hamburger. Or, alternatively, each brand-new level of total energy is found by adding marginal utility to the previous level of complete energy.
R-1 21-1

When marginal energy is zero in graph (b), complete energy in graph (a) is:

A. likewise zero.
B. neither rising nor falling.
C. negative.
D. rising, however at a declining price.

4. FIGURE 21-1 Total and marginal energy Curves TU and also MU are graphed from the data in the table. (a) As more of a product is consumed, full energy rises at a diminishing price, reaches a maximum, and also then declines. (b) Marginal utility, by definition, shows the changes in complete utility. Thus marginal utility diminishes through enhanced usage, becomes zero once full energy is at a maximum, and also is negative when complete energy declines. As shown by the shaded rectangles in (a) and (b), marginal energy is the adjust in total energy associated via each included hamburger. Or, alternatively, each new level of total utility is uncovered by including marginal utility to the previous level of complete energy.
R-1 21-1

Suppose the perchild stood for by these graphs experienced a diminiburned taste for hamburgers. As a result the:

A. TU curve would certainly get steeper.
B. MU curve would certainly get flast.
C. TU and also MU curves would certainly shift downwarD.
D.

MU curve, however not the TU curve, would certainly collapse to the horizontal axis.
