Answer: Option (A) is correct.
Step-by-step explanation:
Current salary = $50,000 at Beaver Falls, Pennsylvania
Offered salary = $60,000 at New York City
So, there is a difference of $10,000 between the current and offered salary and he also knows that cost of living is higher in New York city as compared to the previous job location. Hence, he is not so excited about the new job offer.
The growth rate is calculated on the basis of real terms not in nominal terms. The nominal income of an individual increases from $50,000 to $60,000 but the real income doesn't increases because of high cost of living in New York city.
