Answer:
$522,000
Explanation:
The computation of the total investment spending is shown below:
=  Ending unsold cars and trucks valued -  opening unsold cars and trucks  valued + repairing cost + cost of new copy machine
= $900,000 - $400,000 + $20,000 + $2,000
= $500,000 + $22,000
= $522,000
The stock should not be considered while computing the investment spending. Hence, ignored it
