So here we're talking demand, right? and we have income, we have bert, we have roger, we have their 1, 2, 3, 4 ,000 levels of income, we have 6, 4, 2, 0, 1, 2, 2, 3, and 4.
00:20
So the idea for a is that the quantity demanded is equal to the quantity demanded by bert plus the quantity demanded by robert.
00:30
If we're at 2, that means, so we are thinking about roger is at 2 and bert is at 3, so this is actually, right, 2 plus 2 is equal to 4, so that one i agree with.
00:46
Now b is clearly incorrect, right? the new quantity demanded would be, well, they're both going to 4 ,000.
00:54
Well, this is now 0 plus 4 is equal to 4, so i like both these answers...
