Answer:
The GDP will increase by $2,000 as a result of these transactions
Step-by-step explanation:
When trying to calculate the increase in GDP caused by a series of transactions, we do not add all the transactions, instead we look at the price of the final good and that is the increase in GDP. In this case the final good is the necklace that the store department sells for $2,000 therefore we will only consider the final transaction. So the GDP will increase by $2,000 as a result of this series of transactions because the final good sold for $2,000.
