The study I linked (https://journals.sagepub.com/doi/full/10.1177/23328584198724...) addresses this in table 1, page 8. Surprisingly, Black pupils get on average $10 less "infrastructure" expenditures, and $150 more "instructional" expenditures compared to White. The table breaks the spending down into 5 different categories, but in all of them, the differences are negligible. The $150 instructional expenditure difference is the largest.
