Can somebody please walk me through these.

Yamaha Motor produces a motor For speedboat. Yamaha generates a standard costing system For production costing and control. The standard cost sheet For the motor is: Direct materials (6.0 lb. at $5.00) $ 30.00 Direct m {1.6 hours to $12.00} 19.20 Variable overhead (1.6 hours @ $10.00) 16.00 Fixed overhead (1.6 hours @ $6.00) 9.60 Total $ 74.80 During the year, Yamaha plant had the following actual production activity: Production MSGDOO units A total oF 260,000 pounds of raw materials was purchased at $4.70 per pound. N: beginning inventory oF materials. There were 10,000 pounds of material in ending inventory. The Plant used 82,000 direct Labor; hours at a total cost of $1,066,000. Actual Fixed overhead total $556,000, and actual variable overhead misled. $860,000. Manufacturing overhead is applied on the basis of Standard Direct Lgbngours. Application rates were determined based on 60,000 units and 96.000 Direct Labor. Hours, the plant's practical activity. a. How much diFFerence in NO! is due to the price oF direct material being higher or lower than $5 per pound. b. How much diFference is MCI is due to using more or fewer than 6 pounds of direct material per Subassembly? c. How much diFference in N01 is due to paying more or less than $12 per direct Label; hour'? d. How much diFference in N01 is due to using more or Fewer than 1.6 DLH per subassembly? e. How much diFFerence in MCI is due to spending more or less than $19.00 on direct W305 per Subassembly? F. What is the variable overhead rate variance? g. What is the variable overhead eFciency variance? h. What is the xed overhead budget variance? '1- What is the xed overhead production volume variance
