Answer:
$1,750,000
Step-by-step explanation:
Economic value added (EVA) = Net operating profit after taxes - Invested capital * Cost of capital
Economic value added (EVA) = [($23,000,000 - $18,000,000)*(1 - 0.35)] - [$15,000,000*10%]
Economic value added (EVA) = $5,000,000*(0.65) - $1,500,000
Economic value added (EVA) = $3,250,000 - $1,500,000
Economic value added (EVA) = $1,750,000
Hence, the management add the value of $1,750,000 to stockholders' wealth during 2018.
