Question 6:

a. How much is the slope (variable cost rate per unit), using volume of productions as the single cost driver for the year (show your answer with three decimal places)?

b. How much is the slope (variable cost rate per unit), using 'material A' as the single cost driver for the year (show your answer with two decimal places)?

c. How much is the slope (variable cost rate per unit), using 'material B' as the single cost driver for the year (show your answer with two decimal places)?

d. How much is the slope (variable cost rate per unit), using 'direct labour hours' as the single cost driver for the year (show your answer with two decimal places)?

e. How much is the slope (variable cost rate per unit), using 'machine hours' as the single cost driver for the year (show your answer with two decimal places)?

Please show all working and also use the regression method. Unable to attach excel to the question so have copied and pasted the table to the question.
