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

Let x represent the amount of adult tickets sold
Let 400-x (or 800-2x) represent the amount of student tickets sold

3x + 800 - 2x = 1050

subtract 800 from both sides of the equation

3x - 2x = 250

x=250, 250 adult tickets were sold.

400x=student tickets=400-250=150 student tickets were sold.

A way to check your answer is to check the revenue.

3(250)=750
2(150)=300

750+300=1050
