Three classes of school children are selling tickets to the school play. the number of tickets sold by these classes, and the number of children in each of the classes have been read into these variables:tickets1, tickets2, tickets3 and class1, class2, class3. write an expression for the average number of tickets sold per school child. submit

We know that by employing the formula for the average here, we can find the average number of tickets sold per school child as the ratio of the total number of tickets sold to the total number of children in the school.Let A be the average number of tickets sold per school child.Let T be the total number of tickets sold.Let C be the total number of children in the school.Then from the information provided in the question,T=tickets1+tickets2+tickets3 and C=class1+class2+class3Thus, A can be expressed as:[tex] A=\frac{tickets1+tickets2+tickets3}{class1+class2+class3} [/tex]The above is the expression for the average number of tickets sold per school child.
