Quizplus · Accepted Answer

To find the marginal utility of the fourth cup of coffee, we need to subtract the total utility of the third cup from the total utility of the fourth cup.

Total utility of the third cup = 37 utils 
Total utility of the fourth cup = 46 utils

Marginal utility of the fourth cup = Total utility of the fourth cup - Total utility of the third cup 
= 46 - 37 
= 9 utils

Therefore, the marginal utility of the fourth cup of coffee is 9 utils.
