(a) For each year, except as provided by Sections 46.005 and 46.006, a school district is guaranteed a specified amount per student in state and local funds for each cent of tax effort, up to the maximum rate under Subsection (b), to pay the principal of and interest on eligible bonds issued to construct, acquire, renovate, or improve an instructional facility. The amount of state support is determined by the formula:
FYA = (FYL X ADA X BTR X 100) – (BTR X (DPV/100))
