John likes Coca-Cola. After consuming one Coke, John has a total utility of 10 utils. After two Cokes, he has a total utility of 25 utils. After three Cokes, he has a total utility of 50 utils.Does John show diminishing marginal utility for Coke, or does he show increasing marginal utility for Coke?

Respuesta :

Answer:

No, he doesn't show diminishing marginal utility. Yes, he shows increasing marginal utility for Coke.

Explanation:

The law of diminishing returns states that the marginal or addition satisfaction or utility derived from the consumption of a product increase until a pint and then starts to  decrease.

Units         Total utility       Marginal utility

1                    10                          10        

2                   25                         15                    

3                   50                         25

After 3 bottles, John does not show diminishing marginal utility as the marginal utility (as shown above) continues to increase with each additional bottle of coke consumed.
