Default two-variable data table question

I must really be dense or something because I'm not getting this at all. If
the 1-10 is not subtracting, then what number is being multiplied by B2?

What you are seeing in the copied spreadsheet is the entire spreadsheet.
There are not 10 rows, 10 columns, nor 10 figures, so I still don't
understand what the
1-10 relates to in the formula.

Thanks for the continued help.

It's not 1 minus 10, it's 1 - 10*B2
(Remember that multiplication has precedence over subtraction in the
precedence of arithmetic operators).


If you don't understand where the 10 comes from, how many percent do you
reduce A3*1% by for every 1% change in row 2?

I figured the 1-10 meant 1 minus 10, but I don't know where that's
coming from. I don't see 10 of anything in the spreadsheet, so what
is the 1 minus 10 relating to?

I have inherited the spreadsheet below containing a two-variable
data table. Can someone tell me what the 1-10 portion of the
formula means; I can't find what it is relating to.


The formula in cell B2 is: *=A3*1%*(1-10*B2)


* * *A * * * * *B * * * * * * C * * * * * * * D * * * * * * *E
F * * * * * * *G
1 * * * * * * * Expense vs. Sales
2 * * * 0 * * * 1% * * *2% * * *4% * * *6% * * *8%
3 Sales $1,000,000 * * *9000 * *8000 * *6000 * *4000 * *2000
4 * * * $2,000,000 * * *18000 * 16000 * 12000 * 8000 * *4000
5 * * * $3,000,000 * * *27000 * 24000 * 18000 * 12000 * 6000
6 * * * $4,000,000 * * *36000 * 32000 * 24000 * 16000 * 8000
7 * * * $5,000,000 * * *45000 * 40000 * 30000 * 20000 * 10000


Thanks for the help.




The "10" in that phrase is a constant, given by the designer of the
formula. You should ask the designer where and why does 10 come from?
If you are familiar with analytical calculus, any equation of type a*x
+b means a straight line in Cartesian coordinates, where "a" & "b" are
constants. HTH
