Answer:
The MPC (Marginal Propensity to Consume) in Normalia = 0.9
The MPS (Marginal Propensity to Save) in Normalia = 0.1
A South Pangean household will increase their spending by $70
Explanation:
In Normalia if income increases by $100 and all households increase their spending by $90 that would mean for every $100 they earn they will spend (consume) $90 = 0.9. Which means they have $10 left so they save 10% leaving their MPS to be 0.1. For the households in South Pangea if they have a MPC of 0.7 that means if they have $100 they will spend $70.
