Answer:
$153,750
Explanation:
The computation of the allocated standard overhead cost is shown below:
= Number of Actual units produced × (Variable manufacturing overhead cost​ per unit + Fixed manufacturing overhead cost​ per unit)
= 15,000 units Ă— ($3.75 per unit + $6.50 unit)
= 15,000 units Ă— $10.25 per unit
= $153,750
This  (Variable manufacturing overhead cost​ per unit + Fixed manufacturing overhead cost​ per unit) is also known as standard cost per unit
