1 answer

To create the equations representing the situation for Georgia Connections Academy's Spring Fling tickets, we have the following information:

  1. Adult tickets cost $4 and student tickets cost $2.50.
  2. The total revenue from ticket sales is $2,820.
  3. The total number of tickets sold is 900.

Let’s break it down step by step.

Step 1: Write the Equation for Revenue

The revenue from adult tickets and student tickets sold can be expressed using the equation:

\[ 4a + 2.5s = 2820 \]

Step 2: Write the Equation for Total Tickets Sold

The total number of tickets sold can be expressed using the equation:

\[ a + s = 900 \]

Blanks Filling

Using the information above, we can fill in the response areas as follows:

  1. For the revenue equation (\(4a + 2.5s = 2820\)):

    • Fill in the first response area with 4, the second response with 2.50, and the last response area with 2820.
  2. For the total tickets sold (\(a + s = 900\)):

    • Fill in the first response area with s and the second response area with 900.

Final Answer

Now, substituting values, we summarize the filled equations:

  1. Revenue: \[ 4a + 2.50s = 2820 \]

  2. Total Tickets: \[ a + s = 900 \]

Solving the System of Equations

To find the number of adult \(a\) and student \(s\) tickets sold, we can solve this system of equations.

From the total tickets equation (\(a + s = 900\)), we can express \(s\) in terms of \(a\): \[ s = 900 - a \]

Substituting this into the revenue equation: \[ 4a + 2.50(900 - a) = 2820 \] \[ 4a + 2250 - 2.5a = 2820 \] \[ 1.5a + 2250 = 2820 \] \[ 1.5a = 570 \] \[ a = \frac{570}{1.5} = 380 \]

Using \(a = 380\) in the total tickets equation: \[ s = 900 - 380 = 520 \]

Conclusion

  • Adult tickets sold: 380
  • Student tickets sold: 520

So the final answer is:

  • Adult tickets: 380
  • Student tickets: 520
