Answer

Explanation:

Step1: Recall marginal - utility formula

Marginal utility of the $n$th unit = Total utility of $n$ units - Total utility of $(n - 1)$ units.

Step2: Identify values for $n = 4$

Total utility of 4 units is 50, and total utility of 3 units is 45.

Step3: Calculate marginal utility

Marginal utility of the 4th unit = $50−45$. $50 - 45=5$
