题目

A company has a process in which the standard mix for producing 9 litres of output is as follows:   

                                                                                               $ 

4.0 litres of D at $9 per litre                                         36.00 

3.5 litres of E at $5 per litre                                         17.50 

2.5 litres of F at $2 per litre                                            5.00 

Total                                                                                  58.50 

A standard loss of 10% of inputs is expected to occur. The actual inputs for the latest period were:   

                                                                                              $ 

4,300 litres of D at $9.00 per litre                             38,700 

3,600 litres of E at $5.50 per litre                             19,800 

2,100 litres of F at $2.20 per litre                               4,620 

Total                                                                              63,120 

Actual output for this period was 9,100 litres.  

What is the total materials mix variance? 

A

$2,400 (A) 

B

 $2,400 (F) 

C

 $3,970 (A) 

D

 $3,970 (F)
