.To raise money for a charity, students in a fifth grade class organized a competition at the school's picnic. They filled a big jar of jelly beans and

other students and their parents were asked to guess how many jelly beans were in the jar. The person whose guess was closest to the real

number received a prize and, of course, the jar of jelly beans. To enter the competition, they charged adults 125 and children 75. Back in

their classroom, they counted the money and learned that they had earned 6, 275 from the competition. A total of 65 people had made a

guess. How many parents and children had entered the competition?
