Problem 3 (2 points): Consider the macroeconomic model defined by National income: Y = C + I + G* (G* > 0)
Consumption: C = aY + b (0 < a < 1, b > 0)
Investment: I = cr + d (c < 0, d > 0)
Money supply: MS* = k1Y + k2r (k1> 0, k2< 0, MS* > 0)
Show that this system can be written as Ax = b, where

a/ Use Cramer’s rule to find C;
b/ Then write down the money supply multiplier for C and deduce its meaning

i got 10.28 but that rounds up to 10.3

step-by-step explanation:

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
