To your point about my math, it was a "quick & dirty" estimate of how much such a cost would amount to "per person." The actual way that public schools are funded is via property taxes, i.e., per household, not per person. (Property taxes are the primary way schools are funded, although local schools might receive supplemental state or federal funds.) FYI, whether directly through homeowners' property taxes or indirectly through rent, all residents fund their local public schools, regardless of whether a) they have children in public school; b) have children in private school (funding public school via taxes and private school via tuition), or c) they have no school-aged children or no children at all. It's considered a benefit to society at large to have an educated citizenry, with a public school system to provide for that. I didn't create the system: it's just the way it is. P.S. Actually, my hypothetical per person cost was overestimated, as an area's businesses pay property taxes, too.
