Let's say the Boosters sell x hot dogs and y pretzels.

The income from selling hot dogs would be 4x dollars.
The income from selling pretzels would be 2y dollars.

To reach their goal of $800, the equation becomes:
4x + 2y = 800.

Since they have 300 hot dogs and pretzels in stock, the equation also becomes:
x + y = 300.

We can solve this system of equations:

Multiply the second equation by 2:
2x + 2y = 600.

Subtract the second equation from the first:
(4x + 2y) - (2x + 2y) = 800 - 600,
2x = 200,
x = 100.

Plug the value of x back into the second equation:
100 + y = 300,
y = 200.

Therefore, the Boosters need to sell 100 hot dogs and 200 pretzels to reach their goal of $800. Answer: 100 hot dogs and 200 pretzels.
