Prudie’s estimate for June was slightly off. Her company actually cleaned 34 parking lots in June. For these 34 parking lots, her employees used a total of 323 gallons of detergent. This detergent actually cost the firm $24,871 in total. Also assume that these 34 parking lots actually required 362 DL hours at a cost of $3,258. Actual VOH costs in June amounted to $2,172.

Calculate the June total flexible budget DM variance for the detergent. Represent this variance as a positive number.
