The Jefferson Davis Parish School Board in its regular monthly meeting last night approved an increase in school lunches at five parish schools. The biggest increase will be at Jennings High School, where a 10-cent increase, or a total of 30 cents per day, will be charged. The others, all 5-cent increases bringing the cost of school unties to 25 cents, were Jennings Northside, Jennings Ward Elementary, Lacassine High School and Lake Arthur High School.
