Quizplus · Accepted Answer

Since the marginal utility of consuming the third bar is 20, the total utility derived from consuming three chocolate bars can be found by subtracting the total utility of consuming two chocolate bars (25) from the total utility of consuming three chocolate bars: 
Total utility of three bars - Total utility of two bars = 20
Total utility of three bars = 20 + 25 = 45. Therefore, the best choice is option C, with a total utility of 45 units from consuming three chocolate bars.
