I am trying to perform a suitability analysis based on certain criteria which I have rasters of. I would like to use the Raster Calculator function in ArcMap to determine suitability scores in a given area, with some criteria weighted more than others.

For example, one criterion is income, another is tree canopy percentage, and a third is percentage of vacancies. I'd like to give a equal ranking/weight to tree canopy and vacancy and half weight to income.

How should I input this into the raster calculator?

I do understand that if I wanted to give all equal weight I would just input: "treeCanopy" + "vacancy" + "income" and get my resultant scores in the output raster.

You could use the tools "weighted sum" or "weighted overlay" for this if you have the licenses:
