Answer:
a. only if the increase in her nominal income is less than six percent.
Step-by-step explanation:
Inflation describes the rate of price increment in the economy over time. A rise in inflation means that the prices of goods and services in the country are also rising. High inflation erodes the purchasing power of a currency.
Norma will not feel the effect of an increase in her income if the rise is lower than the inflation rate. An inflation rate of 6 per cent means that the prices of good and service have gone up by that 6 per cent. Her purchasing power is lower by 6 per cent. For an increment in income to benefit her, it must be above the inflation rate.
