Answer:
- total variance: -$20
- favorable
Explanation:
The estimated cost is ...
$14000 +12600 +6200 = $32800
The actual cost is ...
$13860 +12420 +6500 = $32780
The variance is the difference between actual cost and predicted cost:
$32,780 - 32800 = -$20.
It is favorable when actual costs are lower than predicted.
