using multiple parameters in calculation

I have a requirement I'm not sure how to implement.

We have a table of devices we need to upgrade to a new software version. however, each location will be able to upgrade a different number of devices in one week. I need to be able to run what-if scenarios where I increase/decrease the number of upgrades in a city but keep the others constant to get estimates on how long it will take to upgrade each location.

this is a simplification of my data:

using the serial number to get a count of devices in each location

my thought is that I would create a parameter for each location and then use those parameters in a calculation,

Each parameter would have a value from 1 to 5 for example in 1 increments.

But I'm not sure how to properly filter the results for to get a table result like the following

where via a slicer i can change the number of devices per week in NY alone.

in pseudo code I imagine this to look something like this:

if location = NY then divide Devices by "NY Devices/Week parameter"

elseif location = LA then divide Devices by "LA Devices/Week parameter"

else divide Devices by "HOU Devices/Week parameter"

but not sure how to translate that into DAX.
