Assume the following model of the economy, with the price level fixed at
1.0:
C = 0.8(Y – T) T = 1,000
I = 800 – 20r G = 1,000
Y = C + I + G (M/P)S = (M/P)d = 0.4Y – 40r
MS = 1,200
A) Write a numerical formula for the IS curve, showing Y as a function of r
alone.
B) Write a numerical formula for the LM curve, showing Y as a function of
r alone.
C) What are the short-run equilibrium values of Y, r, Y – T, C, I, private
saving, public saving, and national saving?
D) Assume that G increases by 200. By how much will Y increase in shortrun equilibrium?
E) Assume that G is back at its original level of 1,000, but MS
(nominal
money supply) increases by 200. By how much will Y increase in short-run
equilibrium

Ican interpret and represent the remainder in division calculations sensibly for the context (eg if we wont to know how many 40 seat buses will be needed to transport 170 students for on excursion, we divide 170 by 40 and realise buses and another smaller vehicle to that we need 4 transport 10 more students) solve the following questions. show your work! 11) the zoo had 420 butterflies that needed to be transported to a new enclosure. the boxes that the butterflies would be moved in only hold 80 butterflies in each. how many boxes would they need? 2 12) each classroom in the school can have exactly 25 students, if there are 345 students in the school how many full classrooms are there?
