Pretend that you do not know algebra.
A school play charges $2 for students and $5 for adults. For the three days of the play, 20 tickets were sold and $85 was raised. How many student tickets were sold?
There are 20 tickets total.
Let a represent the number of adult tickets and s represent the number of student tickets.
Then, a + s = 20 because the sum of the number of adult and student tickets is 20.
Since each adult ticket costs $5, all of the adult tickets sold have a value of 5a. And, since each student ticket costs $2, all of the student tickets have a value of 2s. The total value is $85, so 5a + 2s = 85.
The number of adult tickets is 20 – s. Substitute this value into the second equation to find the value of s. 5(20 – s) + 2s = 85.
Show and explain the algebra steps.
Answer the question in the problem. There were 15 adult tickets and 5 student tickets sold for the play.
