Answer:
$450 U
Explanation:
Spending Variance for Supplies = Standard Cost - Actual Cost
Standard cost formula = $1,200 per month + $20 per frame
Standard cost for actual output = $1,200 + ($20 [tex]\times[/tex] 610)
= $1,200 + $12,200
= $13,400
Actual cost = $13,850
Spending Variance = $13,400 - $13,850
= -$450 Unfavorable
Since the value is negative the variance is unfavorable as actual cost is more than standard cost of the product.
