Answer:
$864,400
Step-by-step explanation:
The computation of the total period cost for the month under variable costing is shown below:
= Variable selling & admin expense + fixed manufacturing overhead + fixed selling and admin expense
= ($15 × 13,000 units) + $500,400 + $169,000
= $195,000 + $500,400 + $169,000
= $864,400
