No recipient shall be required to work in excess of eight (8) hours per day, nor in excess of forty (40) hours per week. The actual number of work-training hours required shall be determined by dividing the total grant of the recipient received under the general public assistance program (GPA), by the then-prevailing minimum wage. The grant of each recipient shall then be increased by the amount of thirty dollars ($30.00) per week, or a portion thereof proportionate to the number of hours actually worked compared to a standard forty-hour (40) week. The increase shall be considered to result from the recipient’s participation in the program, and shall be included in determining the number of hours to be worked.
