Intermediate: Cost behaviour

(a) From the above data you are required:
(i) to prepare a schedule to be presented to management showing for the mileages of 5000, 10 000, 15 000 and 30000 miles per annum:
(1) total variable cost (2) total fixed cost (3) total cost (4) variable cost per mile (in pence to nearest penny)
(5) fixed cost per mile (in pence to nearest penny)
(6) total cost per mile (in pence to nearest penny)
If, in classifying the costs, you consider that some can be treated as either vari¬ able or fixed, state the assumption(s) on which your answer is based together with brief supporting reason(s).
(ii) on graph paper plot the information given in your answer to (i) above for the costs listed against (1), (2), (3) and (6).
(iii) to read off from your graph(s) in (ii) and state the approximate total costs applic¬ able to 18 000 miles and 25 000 miles and the total cost per mile at these two mileages.
