Answer:
$1,050
Step-by-step explanation:
Value Added Approach to calculating the GDP avoids double counting by adding only the value addition of all firms in an economy to obtain the GDP. Value addition for each firm can be calculated by deducting the intermediate purchase of each firm from its intermediate sales as follows:
Firm X value addition = ($250 * 3) - $400 - $200 = $750 - $600 = $150
Firm Y value addition = ($250 * 4) - $250 - $250 = $1,000 - $500 = $500
Firm Z value addition = (500 * 2) - $100 - $500 = $1,000 - $600 = $400
Therefore, we have:
The economy's GDP = $150 + $500 + $400 = $1,050
