Answer:
The activity variance for supplies cost in March would be closest to $24 (Unfavorable)
Step-by-step explanation:
The activity variance for supplies cost in March is calculated below
Activity variance = Planning Budget - Flexible Budget
= ($1,700 + ($8 * 610)) - ($1,700 + ($8 * 613))
= ($1,700 + $4,880) - ($1,700 + $4,904)
= $6,580 - $6,604
= $24U
The flexible budget is greater than the planning budget. Therefore, the variance is unfavorable (U)
