electure — it was a going to be a trick question for Monday's quiz.

Roger,
I guess I have to start reading the whole post before inserting foot in mouth. Sorry.

Roger,

that is the answer I get and the way the book shows to do it,except they round to 115.5 and thus get an the answer 'C', whereas I get 'B', but back to my original question...What are the rules for rounding?
I don't know the test is going to force me to round up to tenths. But I guess with all the input the answer is.. there is no official rule and if any questions get this close and I get it wrong, I'll have to submit an official protest.

And sorry, meant 220-2(b), but i know you knew that already.

Thanks all!!
