We are working with solving multi-step equations with one variable. I need to write an equation to solve the following:
The attendance at a baseball game was 400 people. Student tickets cost $2 and adult tickets cost $3. Total tickets sales were $1050. How many tickets of each type were sold?
I can't figure out what the equation should be using x to represent the number of tickets.
Since 400 people attended, it's safe to assume that a total of 400 tickets were sold
Let the NUMBER of student tickets sold, be x
With 400 tickets being sold, and with x being the number of STUDENT tickets sold, the number of ADULT
tickets sold = 400 - x
With each student ticket costing $2, proceeds from the sale of student tickets = 2x
With each adult ticket costing $3, proceeds from the sale of adult tickets = 3(400 - x)
Now, since total proceeds from sales was $1,050, then we can say that:
2x + 3(400 - x) = 1,050
2x + 1,200 - 3x = 1,050
2x - 3x = 1,050 - 1,200
- x = - 150
x, or number of student tickets sold =
, or 
You should be able determine the number of adult tickets that were sold
