So first of all, let's, let me try to paint you a picture of diminishing marginal utility, right? so if we plot, say, the number of goods and the utility, diminishing marginal utility says that the curve gets flat, right? it gets flatter.
00:21
The idea here, right, is diminishing marginal utility.
00:26
So diminishing is shrinking.
00:35
Marginal means the last or next unit.
00:42
So what diminishing marginal utility is saying is that each unit gives you less utility, right? each provides less.
00:54
So the line is getting flatter and flatter and flatter because each unit is giving you less of a bump to utility.
01:00
So the correct answer here is a.
01:05
As a person consumes more and more of a good, right, as they increase their consumption, the addition to total satisfaction decreases, right? yet the amount you're adding on, the amount of an extra bump you're getting is shrinking towards zero.
01:20
It has nothing to do with income, right? nothing to do with income.
01:23
It's about utility, so b is wrong.
01:25
It's not c because c has it going the other way.
01:28
It would be increasing marginal utility, right? c is increasing marginal utility.
01:33
And again, d is wrong because there's nothing to do with income.
01:37
So for quincy, right? for quincy, what do we know? quincy eats less ice cream and more pretzels...
