I can't understand question 33?
q is the acres he moves and he needs to work 2 hours (L) to get 1 q if you where to use q=2L and plugging in 2 for L you would get 2 so you need to q=0.5 L and when you plug 2 in that should give you 1
I found 9 and the answer is 6 can someone please explain it to me ?
MR=105-10q1-5q2=15 10q1=90-5q2 q1=9-0.5q2 q2=9-0.5q1 plug in each other and you get 0.75q1=4.5 q1=6
?
Already done, u got the week 2,3 and 4 here on study drive
i know but nothing for 5,6,7
Tiny mistake. There needs to be a minus in front of the left term.
A natural monopoly has a strictly decreasing average cost curve so it should be a
Why is it answer C) and not D)?

Can anyone help me to solve question 18?
U=X+3Z which mean you get 1 point of utility from 1 good x and 3 points of utility from 1 good z. Y=10, Px=0.5 and Pz=2 always try the two extremes first so max amount of one good and then max amount of other while the other is 0. 10=0.5x x=20 and 10=2z z=5, Put the quantities back into the utility function to see which combo gives most utility given budget constraint in this case its 20, Other way is MRT=MRS
Anyone has has an econlab key that I can borrow? Please? First one who gives me the code gets a sandwhich at SBE. Thank you. Message me +31640773190

Why is -2 + 0.67 = -1.2?
MRuk= MRge Puk(1+ 1/E) = Pge (1+ 1/E); Where E stands for elasticity Puk=3Pge For Germany; Pge(1+1/-2)= 0.5 Pge UK; 3Pge(1+1/E)= 0.5Pge times 2, divide by Pge 6+6/E =1 6/E = -5 Euk = -6/5= -1.2

awesome summary
How to solve it?
Hi Anonymous Letter, I attach my solution. In this question, we first have to find the price that will arise in this monopoly and then use the formula for the Lerner Index Hope that helps! Best, Your Success Formula Team - Wojtek
Can somebody explain why the answer is b?
Hi Anonymous Letter, Here, we see 3 different demand curves - one intersecting at q=10, one at q=20 and one at q=40. The differences arise here because of the different prices of snacks in each of the scenarios: 1) Intersection at 10 => buying 0 juice Bobby can afford 10 units of snacks. As he has 20 euros to spend, it means the price per unit of snacks is 20/10=2. Then, the demand is tangent to the utility function where q=5 so we find one point of his demand curve to be p=2, q=5. 2) Intersection at 20 => p=20/20=1. Then tangent to the utility for q=7. So p=1, q=7 another point on the demand curve. 3) Intersection at 40 => p=20/40=0.5. Then tangent to the utility for q=10. So p=0.5, q=10 another point on the demand curve. Thus, we see that answer b is one of the possible points we found. Hope that helps! Best, Your Success Formula Team - Wojtek

Can please anyone explain 51 and 52?
why c?
because the new supply equation is Qs=10+5(p-2) which is 10+5p-10 so Qs is 5p

q24?
He gets more utility from pizzas(exactly 10 more ) than from beer if he where to spend all his money on beer he could buy 10 which would give him 10 utils but if he where yo spend all his money on pizzas he would get 20 utils which is more than any other combinations
Can somebody please show the calculation?

I don't get how you came to X=20
suppose that you only spend X, then Z should be 0 -> 0.5X=10, X=20
How do you get to 2 units (answer B)?
See ppt. week 7, slide 26 P=25-4Q; P=25-4(Qa-Qb) = 1 (residual demand = MC) for Qb; (25-4Qa) - 4Qb Rb; Qb(25-4Qa)- 4Qb^2 (Total revenue for b; P*Q) MR; 25-4Qa -8Qb (derivative with respect to Qb) MR=MC; 25-4Qa-8Qb=1 4Qa+8Qb=24 Qa=Qb 12Qb=24, Qa=Qb=2
anyone of you who knows why answer c is wrong? the correct one is D
you have to take the mr of the inverse demand not the normal demand function so its P=2000-2Q and MR is double the slope P=2000-4Q
Can somebody explain this question?
What is the correct answer ?
plug q1 into q2 or the other way around q1=4.5-0.5(4.5-.0.5q1) q1=4.5-2.25+0.25q1 q1=2.25+0.25q1 0.75q1=2.25 q1=3=q2 P=12-(q1+q2) P=12-(3+3) P=6
did someone manage to do this question????
The MR-curve is 12-Q (twice the slope of the inverse demand). You set MC = MR or Q^2 = 12-Q -> bring everything on one side (0 = Q^2 + Q - 12) and use the abc-formula to get Q = 3

Still relevant in 2018 ?
would have been relevant if it was 1999, but there are more recent summaries
how do you solve this one?
