Answer:
$2000
Explanation:
The total value added by the art dealer would equal the amount of profit that the art dealer made off of the sale of all the sculptures created by the artist. Therefore to calculate this we must subtract the amount that the artist sold each sculpture for ($1000) from the amount that the art dealer sold each sculpture for ($1200) and then multiply the remainder by the amount of sculptures (10) like so:
$1200 - $1000 = $200
$200 * 10 = $2000
Therefore the total added value of the art was $2000.
