Answer:
MPC = 0.8
MPC = 0.2
Explanation:
Marginal propensity to consume is the proportion of an increase in income that is spent on consumption.
Marginal propensity to consume = increase in consumption / increase in disposable income
Marginal propensity to save is the proportion of an increase in income that is saved.
Marginal propensity to save = increase in savings / increase in disposable income
Disposable income is either consumed or saved. so,
Marginal propensity to consume + marginal propensity to save = 1
Marginal propensity to consume = $64 / $80 = 0.8
Marginal propensity to save = $16 / $80 = 0.2

Answer:
Binding
$100
200
200
Shortage
Explanation:
A price ceiling is when the government or an agency of the government sets the maximum price for a good.
A price ceiling is binding when the price ceiling is below the equilibrium price.
To find the equilibrium price, equate qs to qd because at equilibrium, quantity supplied is equal to quantity demanded.
2P = 300 - P
3P = 300
P = 100
Equilibrium price is $100.
$100 > $90. Therefore, price ceiling is binding.
To find quantity supplied, plug in the value of P into the equation for quantity supplied
QS = 2(100) = 200
To find quantity demanded, plug in the value of P into the equation for quantity demanded
QD = 300 - 100 = 200
when price is below equilibrium price, quantity demanded increases while the quantity supplied decreases. This leads to a shortage.
