Answer:
a) Operating income - $33,800
Step-by-step explanation:
The flexible budget would be prepared for a different activity level of 6,300 production units but using the assumptions of the fixed budget
$
Sales revenue - ($7× 6,300 units ) : 44,100.00
Less Variable cost - ($1 × 6,300 units ) : ( 6,300)
Contribution 37,800
Less Fixed costs (4,000)
33,800
Note that the fixed costs of $4000 remains the same for both the static and flexible budgets. This is because the activity level of 6,300 units of the flexible budget remains within relevant range. So the fixed cost would not change.
