Marginal utility can: Group of answer choices be positive or negative, but not zero decrease, but not become negative be positive, negative, or zero increase positively, but not negatively

be positive, negative, or zero

Explanation:

Marginal utility is the additional utility derived from consuming one more unit of a good

the consumption decision is to consume more units of a good that gives the higher utility per good.  

Marginal utility = change in total utility / change in units consumed.

When marginal utility is positive, it means that increasing consumption by one unit increases total utility

When marginal utility is negative, it means that increasing consumption by one unit decreases total utility

When marginal utility is zero, total utility has reached its maximum and no more units of goods would be consumed

An example of marginal utility. Imagine a traveller arriving from the desert where he hadn't had a drink of water in days .he is offered his first glass of water. the first cup of water he drinks would give him the highest utility. As more and more cups of water is drank, marginal utility decreases. At the point where he is fully satisfied, he stops drinking water and marginal utility becomes zero.

if kj of heat is transferred o 1200 g liquid water at 36'c, what would the new temperature of the water be? (he specific heat capacity of liquid water is 4.186 j/g''c)

a. 15'c

b.100'c

c.51'c

d.36'c
