Answer:
$9,000
Step-by-step explanation:
Data provided:
Value added by miner = $1000
Value added by iron smelter = $3500
Selling price of the car = $9000
Here,
The selling price of the car already include the values added by the miner and the iron smelter
Now,
The Addition to GDP
= Value added by miner and iron smelter + Value added by manufacturer
= $1,000 + ( $3,500 - $1,000 ) + ( $9,000 - $3,500 )
= $1,000 + $2,500 + $5,500
= $9,000
