Answer:
$8,331 Favorable
Step-by-step explanation:
The computation of activity variance for plane operating costs is shown below:-
For computing the activity variance for plane operating costs we need to find first the expected cost which is shown below:-
Expected cost = $36,240 + ($2,058 × 84) + (1 × 239)
= $36,240 + $172,872 + 239
= $209,351
Activity variance for plane operating costs in October = Expected - Actual
= $209,351 - $201,020
= $8,331 Favorable
