Hi,

I have come across the same sort of question in all of my practice exams but have not been taught the way to solve it!! And I can't for the life of me figure it out myself!

This is how the question is set out...

Complete the table below by inserting all costs for the activity levels of 3,000 and 7,000.

3,000 units 3,500 units 5,000 units 7,000 units

Variable cost

Fixed cost

Total cost 22,500 27,000

Can someone PLEASE help me on how to work these questions out?? I'm baffled!!!!

Many thanks

191AAT StudentDo you mean for 5000 and 7000 units? or is it 3000 and 7000 units. The spaces disappears so the numbers are no longer shown in the correct column once you post.

191AAT Student5RegisteredThe total costs already given are for 3,500 units (total £22,500) and 5,000 units (total £27,000)

191AAT StudentCalculate VC and FC for 3500 and 5000 units first then you can use the answers to complete 3000 and 7000 units.

The high/low method means using the highest level of activity and the lowest level of activity and their corresponding total cost. Here you have only two 3500 and 5000 units (there is no choice) but often you will be given 3 or 4 to pick from. The level of activity in this example is production level in units.

5000 units is the highest level at total cost £27,000

3500 units is the lowest level at total cost of £22,500

You can look up the formula for high/low method, the result is

£27,000 - £22,500 =5000units - 3500units

£4500 / 1500 units = £3 per unit (this is variable cost per unit)

Substitute this in either 3500 or 5000 units.

e.g. 3500

VC 3500 units x £3 = £10,500

FC............................

TC.............................= £22,500

Therefore FC = £12,000

You can check with 5000 units

VC 5000 units x £3 = £15,000

FC............................= £12,000

TC...........................= £27,000

You have worked out VC = £3 per unit and FC = £12,000 and can now complete the costs for 3000 and 7000 units

3000 units:

VC 3000 units x £3 = £9000

FC.......................... = £12,000

TC.........................= £21,000

7000 units:

VC 7000 units x £3 = £21,000

FC...........................= £12,000

TC...........................= £33,000
