(1a)
Average propensity to consume (APC)
Total National consumption/Total National Income = C/Y

Total National Income(y) = #60million
Total national Consumption (c) = #40million
APC = #40m/#60m = 0.66
= 0.7

(1aii)
Average propensity to save(APS)
= Total National Savings/Total National Income = I/Y
Total income = ₦60m
Total expenditure = ₦40m
Total savings = (Total income – Total expenditure)
S = (₦60m – ₦40m) = ₦20m
APS = s/y = ₦20m/₦60m
= 0.3

(1bi)
Marginal Propensity to consume (MPC )
= change in consumption/change in income = Δc/Δy

Initial income = ₦42m
New income = ₦58m
Change in income = (58 – 42) = ₦16m
Δy = ₦16m

Initial consumption(c) = ₦24m
New Consumption = ₦32m
Changes in consumption = (₦32m – ₦24m) = ₦8m
MPC = Δc/Δy = ₦8m/₦16m = 0.5

(1bii)
MPC + MPS = 1
MPS = 1 – MPC
MPS = 1 – 0.5
MPS = 0.5

(1biii)
Multiplier (k)
K = 1/1 – MPC = 1/1 – 0.5
= 1/0.5 = 2

(1ci)
If MPC = 0.75
Multiplier (k) = ?
K = 1/k – MPC = 1/1 – 0.75
= 1/0.25 = 4
Multiplier k = 4

(1cii)
k = Δy/Δc as K = 4
4 = ₦800m/c
4c = ₦800m/4 = ₦200m
C = ₦200m
