RAM + apps lot memory

I need to write business case for one client who has Lenovo T14 laptop with 16GB of RAM.
Is true now days apps like MS Teams, Google Chrome, outlook, MS defender, PDF, Ms Edge, Webex all running at same time for like 4-7hrs are constantly using RAM.
I noticed RAM is being used most at 70-85% constantly and CPU only goes like 4-20%..
I am trying to build case where now I see 16GB is not much now days and would having either 24-32GB be sufficient?
Is there anyway to find out from manufacture like MS, Cisco, google to convince my manager that RAM is main issue here?
He thinks laptop is fine and it has 16GB and intel CPU to be efficient..

having empty ram sitting around is really a waste. even if apps don't use it, the OS will use it as a cache to speed things up. is there a performance issue, complaints from users, some process that is taking too long? what problem are we trying to solve here

I noticed ram when all apps are open is string sound 70-85% and session lasts few hours a week. I been noticing apps are using more ram then cpu.. cpu hardly being touched…

But that's not a problem to be solved. RAM being utilized isn't a problem. What is the problem that caused you to go look at how much RAM was being used? Similarly, you wouldn't open event viewer when you're having no issues and just start randomly trying to address any errors you see.

Laptop fan seems running lot and I can hear fan noise… but I know chrome uses lot memory..
Can ram be constantly being used cause laptop to slow down during meeting and having app open.

If RAM usage is at peak, paging will be used which can considerably slow the laptop down.

Maybe you have a cooling issue. Do you know how to check CPU temperatures? An overheating CPU will definitely slow down

Memory doesn't really get that hot. GPU and CPU get hot. Running out of available memory can cause a computer to be slower, but using a good amount (but not pegged) is usually OK. It is very common for util to hover around 80-85% utilization on my machine and its as fast as ever.

If you manager won't approve a laptop upgrade for pocket change - there's probably a message in there for you. FYI - more memory isn't a solution.

It really depends on the user and the use; it also depends on what's already installed, how many DRAM slots exist and how many are in use, whether it's soldered.
Now, suppose your user has a job in Marketing and is a heavy user of a few select Adobe products. Like Adobe or not, Adobe is a pig. More RAM, 32GB to start with. Or the user is a design engineer and uses Autodesk Revit between 50% and 75% of the day; Revit is another pig... more RAM, 32GB for starters, and at least a higher-end i7 CPU (core count matters). Suppose the user uses Excel exclusively... small spreadsheets? 16GB works fine. Large spreadsheets? More RAM might help, but are large spreadsheets the rule, or the rare exception?
In short, details matter. Not all laptops are created alike, and you can't shoehorn all users into a single model. You almost have to customize a laptop to a user's duties, then account for that user in 3y time.

2 and we have two sticks installed. 8GB each

Is this your laptop?
The frustrating thing is the upselling that manufacturers do to laptops. They will stick 32GB of RAM only in their "high end" machines, so you need to purchase a better processor, GFX, touch Display, etc. All I want is a base model with 32GB of RAM and an ethernet port, it does not exist. Now they are soldering in RAM and provide no extra slots so you can't upgrade the cheapest part on the machine.
At the end of the day performance is what ever the end user is willing to put up with. If the client does not like the performance then they can pay for a 32GB machine. There is no more use case you need to create. If you manager is roadblocking there is no way to fix that. Just make sure they note you said to get 32GB when the client complains about performance again.
You could create a use case based on wait time. Something like this article. https://www.scalepad.com/blog/the-true-cost-of-slow-computers/

The OS will eventually use all of RAM, because anything unclaimed by applications is used as cache.
