Answer:
$20 million are added to 2006's GDP with $16 million as consumption and $4 million as private investment
Step-by-step explanation:
GDP is the total monetary of good and services produced in a country in a given year.
Y=C+I+G+(x-m)
For the question we're told that during 2006 a leading auto manufacturer produced $20 million worth of mini-vans so Y=$20
So out of the $20 total production, $16 million worth of mini-vans were sold which falls under consumption C=$16
And $4 remained unsold out of the total $20 that was produced in 2006. Therefore, I=$4
