All other costs of operation of the finance commission are to be shared by and included in the budgets of the finance agencies in proportion to the amount of cash receipts of each of those agencies.
(c) The finance commission shall have charge and control of the property known as the Finance Commission Building and use of staff, equipment, and facilities of the finance agencies.
