The 9th graders are selling tickets to raise money for a class field trip. They are selling student tickets for $5 and adult tickets for $9. The 9th graders received a total of $240 from sales. In total, 40 tickets were sold. Write a system to represent this situation. Be sure to define your variables. Use your system to determine how many tickets of each type the students sold.

Total number of adult tickets sold = 10

Total Number of Students tickets sold = 30

Step-by-step explanation:

Let be the number of student tickets sold.

Let be the number of adult tickets sold.

As per the question statement, total tickets sold are 40.

Price of each student ticket = $5

Sales from students' tickets = Price of each students ticket Number of students tickets sold

Sales from student's tickets = 5

Price of each adult ticket = $9

Sales from adult's tickets = Price of each adult's ticket Number of adult tickets sold

Sales from student's tickets = 9

Total sales is done by students and adult tickets is $240 as per the question statement.

Solving equations (1) and (2) using elimination method:

Equation :

Total number of adult tickets sold = 10

Putting in equation (1):

Total number of students tickets sold = 30

Total number of adult tickets sold = 10

Total Number of Students tickets sold = 30

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

the answer is 99.
