Answer:
$0.70 and 3.3
Explanation:
Data provided in the question
Household spending for each additional dollar = $0.70
And, the remaining amount = $0.30
So in the given case,
The marginal propensity to consume (MPC) = household spending for each additional dollar i.e $0.70
And, the Spending multiplier is
= 1 ÷ 1 - MPC
= 1 ÷ 1 - $0.70
= 1 ÷ $0.30
= 3.3
