In your class, 7 students do not receive weekly allowance, 5 students received $3, 7 students revived $5, 3 students revived $6 and 2 students received $8. what is the mean weekly allowance? explain how you found your answer.

7 studentsreceive 0
5 studentsreceive 3thats $ 15
7 studentsreceive 5thats $ 35
3 studentsreceive 6thats $ 18
2 studentsreceive 8thats $ 16

the mean (or the average) can be found by adding up the total amount received and dividing by how many students there were.

so the mean is : (0 + 15 + 35 + 18 + 16) / (7 + 5 + 7 + 3 + 2) =
                           84 / 24 = 3.5 <==
