Let \( x \) be the number of hot dogs sold, and \( y \) be the number of pretzels sold.

We have the following two equations based on the problem:

  1. The total number of items sold (hot dogs and pretzels) must equal 300: \[ x + y = 300 \]

  2. The total income from selling hot dogs and pretzels must equal $800: \[ 4x + 2y = 800 \]

Now, we will solve this system of equations.

From the first equation, we can express \( y \) in terms of \( x \): \[ y = 300 - x \]

Now, substitute this expression for \( y \) into the second equation: \[ 4x + 2(300 - x) = 800 \]

Distributing the 2: \[ 4x + 600 - 2x = 800 \]

Combining like terms: \[ 2x + 600 = 800 \]

Subtract 600 from both sides: \[ 2x = 200 \]

Dividing both sides by 2 gives: \[ x = 100 \]

Now, substitute \( x = 100 \) back into the equation for \( y \): \[ y = 300 - 100 = 200 \]

Thus, the Baynard High School Boosters need to sell 100 hot dogs and 200 pretzels to reach their goal of $800.

The answer is: 100 hot dogs and 200 pretzels
