Answer:
The profit margin earned if each unit requires two machine-hours is 25%
Explanation:
For computing the profit margin, first, we have to compute the estimated overhead rate per unit which is shown below:
Estimated Overhead rate = (Estimated manufacturing overhead costs) ÷ (estimated machine hours)
= ($240,000) ÷ (40,000 machine hours)
= $6 
Now the profit per margin would equal to
= Selling price per unit - direct cost per unit - overhead cost per unit × number of required machine hours
= $20 - $3 - $6 × 2
= $5
Now the profit margin would equal to
= (Profit per unit) ÷ (selling price per unit) × 00
= ($5 ÷ $20) × 100
= 25%
