SC - OP Spelling lesson goods and services question

[Patrick Hood]

role, roll argghhhh!

I agree, spell check has given us all a false sense of security and fun new
ways to spell pensic.  I would attribute that roll/role thing to my
enthusiastic celebrating.

While splitting the bill for cheese sticks and pitchers I wondered how do
you listees come to a fair trade when offering goods and services to fellow
scadians.  Generally I take my time multiply it by how much I make at work
an hour and add the cost of materials.  When I was building houses it was
cost of materials times four or five.  (Four or five depending on our
estimate of what kind of jerk this client could turn out to be.)

I would like to know your thoughts or formulas.
