Answer:
b) rise by about 1 percent
Explanation:
Given that a person's nominal income rises by 5 percent and the price level rises from 125 to 130.
Percentage increase in price level = (130 - 125)/125
= 5/125
= 1/25 = 4%
Difference between rise in the person's nominal income and rise in price level
= 5% - 4%
= 1%
Hence the right option is b) rise by about 1 percent.
