In SKU Classification, instead of using the $$VLookup$$ function $($the formulas in column I$),$

we can use the $$If$$ function to get the same result. Research how to use this function in

Excel help $($Pressing F$1$ in Excel will bring up the help window$).$ Make a copy of the

worksheet $$Database$.$ In the copied worksheet, remove the $$Vlookup$$ functions in

column I, and classify SKU$$s again by using $$IF$$ Function. Hint: the formula in Cell I$6$

should be $=$IF$($H$6<=0\mathrm{.}8,"$A$",$IF$($H$6<=0\mathrm{.}95,"$B$","$C$")).$ Compared with the $$VLookup$$

statement, is the nested $$If$$ statement a more flexible way or not? Why?
