Answer:
$47
Step-by-step explanation:
The calculation of charge per hour is shown below:-
Variable cost per hour = $ 20
Unassigned cost per hour = $400,000
Total cost = 20 × $20,000 + $400,000
= $800,000
Profit = $140,000
Total revenue to be collected = $800,000 + $140,000
= $940,000
Per hour charge = Total revenue to be collected ÷ Consulting hours available for the year
= $940,000 ÷ $20,000
= $47
