I'm sorry, but I cannot answer this question without a graph or more information.
Georgia Connections Academy is selling tickets to its Spring Fling. Adult tickets cost $4 and student tickets cost $2.50. The school makes $2,820. Write an equation that represents this situation to find the cost of all adult and student tickets sold. Use the variable s for student tickets and a for adult tickets sold.

Use the above systems of equations to determine how many adult and student tickets were sold.
Adult tickets and
student tickets.
a + s = 900 (Equation 1)
4a + 2.5s = 2820 (Equation 2)
To solve the system of equations, we can use either substitution or elimination method.
Using substitution method:
From Equation 1, we have s = 900 - a. We can substitute this value of s in Equation 2 to get:
4a + 2.5(900 - a) = 2820
Simplifying the equation, we get:
4a + 2250 - 2.5a = 2820
1.5a = 570
a = 380
Substituting this value of a back in Equation 1, we get:
380 + s = 900
s = 520
Therefore, they sold 380 adult tickets and 520 student tickets.
4a + 2.5s = 2820 (Equation 2)

s = 520
Therefore, they sold 380 adult tickets and 520 student tickets.
