Try this one:
=IF(or(and(B1>43%, B1<57%, A1=2016),and(B1 >57%, A1=2016,istext(E1))), "ID",)
Answer from Aurielle Perlmann on Stack OverflowInline operators such as "&" or "+"
if statement - combining IF, AND, OR expressions in Google Sheets - Stack Overflow
What are things like " ' & * % $ called in Google Sheets?

Apologies for this being a bit more meta than most posts, but I've run into these a couple times and was wondering if there was a better, more SEO-friendly name for them than "in-line operators", and if there was a list of them somewhere that I could bookmark/reference rather than comb through all the documentation.
for those less familiar, & is in-line concatenation so
-
CONCAT("cat","dog") -> "catdog"
-
+"cat"&"dog" -> "catdog"
and + is in-line ... range merging? set joining? I'm not sure, I only use it in "FILTER" to make logical-or combos of constraints (so "copy the rows where col A is 'R' or 'C'" gives the formula +FILTER(A2:Z,(A2:A = "R")+(A2:A = "C") )
Anyhow:
What's the official, searchable name for these operators? Is there a list of them somewhere?
Want to read up on the functions of these things, to really understand when and why to use ""A1"" in a sumif like this or '"&A1' like that in a query formula to look up data that contain the text in A1 - for example.
I know that ? * ~ are called wildcards. But what are " ' & % $ called?
Your formula is almost correct except for the AND operator, the syntax for using AND is as follows: AND(logical_expression1, [logical_expression2, ...]).
I have replicated your data and fix the formula. Please see formula and desired output below
Formula:
=IF(AND(B2=TRUE,D2>50),(E2*0.85),E2)
Data and Output:

use:
=INDEX(IF(B2:B="",,IF((B2:B=TRUE)*(D2:D>50), (E2:E*0.85), E2:E))
Hi,
Im hoping someone might be able to point me in the right direction to make my formula work.>>>
___________________
If (C2 is NOT EMPTY) and (C2-I2 is =>0) then (make A2 green) and (uncheck D2) and (make E2 Empty) and (B3=C2-I2) and (A3=C2+I2)

The above is what I want to happen, but i'm not sure which cells have to have which functions...
Thanks
