calculating commissions for a range of values

[abryan]

Hello, I have read the threads about similar problems on this site, bu
nothing seems to work for me so perhaps I am doing something wrong.

I need to calculate commission varying by range:

.5% of sales up to 100
.75% of sales from 100 to 150
1% of sales above 150

I have tried using the IF function but can't figure out if there is
way to signify "if less than x AND greater than y, then z"

You could reformulate the issue as:
..5% of sales
PLUS .25% of sales over 100
PLUS .25% of sales above 150
Which translates into =a1*0.5% + max(0,a1-100)*.25% + max(0,a1-150)*.25%.
