Answer:
$125,000
Step-by-step explanation:
The computation of monthly income before taxes is shown below:-
Loss in contribution margin = 30,000 units × $ 7
= ($210,000)
Saving in fixed monthly overhead = $85,000
Income before taxes would get decreased = Loss in contribution margin - Saving in fixed monthly overhead
= ($210,000) - $85,000
= $125,000
