Anyone know how to do this question?

1. An increase in investment of $5000 incraesed the equilibrium level of national income by $20000. What is the marginal propensity to consume?
How do I apply the formula. Anyone have formulas? Is Ad the same as C?
2. the answer is 0.75


also how do you do:

Change in Y = k * change in AD
which means k = 20000/5000 = 4.
from the formula of simple multiplier MPS = 1/4 = 0.25
MPC = 1 - MPS = 1 - 0.25 = 0.75

2. the answer is 0.75


also how do you do:

the size of the subsidy is the vertical gap between the two curves so 12 - 10 = $2



and
View attachment 40705

MPS = (600-500)/(2000-15000 = 0.2

k = 1/0.2 = 5

from formula in the first question, 1000/5 = $200

after the changes, it can be determined that a tariff of $2 is imposed on top of world price. before this change, gov revenue was zero meaning no imports were coming into the country. the increase in foreign producer revenue means that its a quota because now 200 imports are allowed
