Hi anyone,

I need help in attaining the relationships between Fixed Costs and Variable Costs (this is for accounting). I hope someone will know what I'm taling about as thsi applies to business, not science.

I can easily derive the relationship of Variable Costs and I get:

Total Variable Costs= y= Ax + B

Variable Costs per Unit= y'= A

so: VCU= d/dx(TVC)

But I cannot see the relationship between Total Fixed Costs and Fixed Costs per Unit.

I can see that their graphs are:

TFC= A

and

FCU= A/x

How are the derived from each other? I am puzzled. Any help would be appreciated. Thanks.
