Answer:
$146,200
Step-by-step explanation:
The computation of flexible budget variance for July is given below:-
Direct materials cost = $86,000 ÷ 10,000 × 12,000
= $103,200
Power = $30,000 ÷ 10,000 × 12,000
= $36,000
Salary of plant manager = $7,000
Flexible budget variance for July = Direct materials cost + Power + Salary of plant manager
= $103,200 + $36,000 + $7,000
= $146,200
