the concert?
write expression and answer

Problem can not be solved

Step-by-step explanation:

* Lets explain how to solve the problem

- A total of 1000 people attended a benefit concert was held to raise

 money for a children foundation

∴ The number of students and adult is 1000

- Student  ticket cost $2 and an adult ticket cost $3

∴ The cost of the student ticket is $2

∴ The cost of the adult ticket is $3

- The organizer raises a total of $5500

∴ The total money earns fro tickets is $5500

- Assume that the number of students who attended the concert

 is x and the number of adults is y

- There are 1000 students and adults attended the concert

∴ x + y = 1000 ⇒ (1)

- The cost of student ticket is $2

∴ The money earned from students is 2 × x = 2x dollars

- The cost of adult ticket is $3

∴ The money earned from adults is 3 × y = 3y dollars

- The total money earned from students and adults is $5500

∴ 2x + 3y = 5500 ⇒ (2)

* Now lets solve the two equation by elimination method

- Multiply equation (1) by -3 to eliminate y

∴ (-3)x + (-3)y = (-3) × 1000

∴ -3x - 3y = -3000 ⇒ (3)

- Add equations (2) and (3)

∴ -x = 2500

- Multiply both sides by -1

∴ x = -2500

∵ x represents the number of the students and never the number

  of student be negative , then the problem can not be solved

my dear correct answer is option number 3
