How to Calculate Variable Cost - cloud5 - 03-31-2011

Given a product has sales 75 000 pound and variable cost 45 000 pound. If the sales increased 40 000 pound, how to find the variable cost?

Ok assuming the variable cost increases at the same rate as revenue i.e. The variable cost per unit remains same than

45000/75000 = 0.6

This means that for each 1 pound sales we incur 0.6 variable cost. Therefore for 105000 sales we will incur 63000 variable cost. This means an excess of 18000 will be incurred for excess sales of 40000 ( 63000-45000 ).

The question in my book given the sales = 75 000, variable cost = 45 000, fixed cost = 25 000, profit = 5 000. Then the sales increased 40 000. The answer for variable cost is 80 000. How to get the answer?

There are two ways of solving that question first one was illustrated earlier and the second one is to suppose that same contribution margin is received on sales
Sales have been increased and become

Sales 115000
Variable Cost(Bal Fig)
Contribution Margin (75000-45000) 30000
Variable cost is 85000.

I have done everything to produce a answer which is 80000 but i am unable to do so
