To determine how many hot dogs and pretzels the Baynard High School Boosters need to sell to reach their income goal, we can set up a system of equations based on the information provided.
Let:
- \( x \) = number of hot dogs sold
- \( y \) = number of pretzels sold
From the problem, we have two equations:
-
The total number of hot dogs and pretzels must equal 300: \[ x + y = 300 \]
-
The total income from the sales must equal $800: \[ 4x + 2y = 800 \]
We can solve these equations step by step.
Step 1: Solve the first equation for \( y \): \[ y = 300 - x \]
Step 2: Substitute \( y \) into the second equation: \[ 4x + 2(300 - x) = 800 \] Distributing the \(2\): \[ 4x + 600 - 2x = 800 \] Combine like terms: \[ 2x + 600 = 800 \] Subtract 600 from both sides: \[ 2x = 200 \] Divide by 2: \[ x = 100 \]
Step 3: Substitute \( x \) back into the first equation to find \( y \): \[ y = 300 - 100 = 200 \]
Therefore, the boosters need to sell 100 hot dogs and 200 pretzels.
So, the correct answer is: 100 hot dogs and 200 pretzels.
