I only need the answer of question 13

Question 2 1 pts Use the below information to answer the remaining exam questions Prudie needs help with budgeting. She provides you with the following data about her costs, revenues, and expected units (# of parking lots cleaned). Assume that Prudie's Pressure Washing budgets 10 DL hours per parking lot and predicts DL wages to be $11 per hour. Also assume that variable overhead is allocated at a budgeted rate of $6 per DL hour, and that FOH is expected to be $9,500 per month. Budgeted revenue per parking lot cleaned is $1,600. The only direct material at Prudie's Pressure Washing is a detergent solution used to clean oil off parking lots. Prudie tells you that her employees budget to use 12 gallons of detergent per parking lot and that the budgeted cost of the detergent is $80 per gallon. Prudie provides you with expected parking lots to be cleaned for the following 4 months. Month Expected Parking Lots (# units) March 32 40 April May 21 June 29 Calculate budgeted monthly break-even sales revenue for Prudie's Pressure Washing. Question 7 1 pts Use the below information to answer the remaining flexible budget variance questions 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 Question 8 1 pts Classify the above flexible budget DM variance. Favorable O Unfavorable Neither favorable or unfavorable Question 11 1 pts Calculate the June flexible budget DM efficiency variance for the detergent. Represent this variance as a positive number. Question 12 1 pts Classify the above DM usagelefficiency variance. Favorable Unfavorable Neither favorable or unfavorable Question 13 1 pts Calculate the June flexible budget DL efficiency variance. Represent this variance as a positive number
