Answer:

Consumption will increase by $960

Explanation:

Consumption Function is a function showing consumption & income relationship, signifying how consumption is dependent on income.

C = a + b.Y ;

where C = Consumption ; a = Autonomous consumption at 0 income level; Y = Income ;  b = Marginal Propensity to consume, i.e Change (addition) in consumption due to change (additional) Income = ΔC /ΔY.

MPC = ΔC /ΔY

Given : MPC = 0.8 , ΔY = 1200

0.8 = ΔC / 1200

ΔC = 1200 (0.8)

ΔC  [Change in Consumption] = 960
