Answer:
a.$7.43 per machine hour
Explanation:
The computation of the single plant wide rate is shown below:
Single plant wide rate = Total overhead cost ÷ Machine hours
where, 
Total overhead cost = $84,000 + $72,000 = $156,000
And, the machine hours is 
= 1,000 units × 5 + 2,000 units × 8
= 5,000 + 16,000
= 21,000 machine hours
So, the single plant wide rate is 
= $156,000 ÷ 21,000 machine hours
= $7.43 per machine hour
