Answer and Explanation:
a)
If you charge $40 for X then everyone will buy as everyone is willing to pay atleast $40. this means all three groups buy that is 3*1000 buyers.So profit from X = 3000*40= $120,000
And since everyone is willing to willing to pay atleast $60 for Y again all three groups will buy so profit from Y =3000*60=$180,000
profits=$300,000
b)
If you charge $90 and $160 for X and Y respectively you will have only 1000 buyers for each product as others are unwilling to pay this much.
So profits = 1000*90 + 1000*160=$250,000
c)
for a bundle of X and Y buyers are willing to pay a total of $150, $210 and $200 across the three categories.
So everyone will buy a bundle of 1 X and 1 Y.
profits = 150*3000= $450,000
d)
If you charge $210 only the second will buy as they are willing to pay that much so profits =1000*210=$210,000
Also by selling X at $90 group 1 will buy X; profits=1000*90=$90,000
and by selling Y at $160 group 3 will buy Y; profits=1000*160=$160,000
total profits =$460,000
