The grant program shall provide one dollar in matching funds up to a maximum amount authorized by the state board for a single charter school project for each dollar donated to a qualified charter school organization for such project; provided, however, that the total amount to a qualified charter school organization for a single charter
school project shall not exceed 75 percent of the average per student state portion of capital outlay funding provided pursuant to Code Section 20-2-260 multiplied by the number of students that the charter school project was designed to serve.
