nested if statements

[Guest]

I need an if statement that looks at a cell for a value and enters the
following:

if the value in cell A1 is between 0 and 30,000 then enter "A1*0.1"
if the value in cell A1 is between 30,000.01 and 60,000, then enter "A1*0.15"

and so on down the line, I know my limit is seven nested, just not sure how
to phrase the statement

works great without the commas in "30,000.01" and "60,000.01"
