50 hot dogs and 250 pretzels

Answer 1

To calculate the number of hot dogs and pretzels needed to reach the goal of $800, we can set up a system of equations:

Let x = number of hot dogs sold
Let y = number of pretzels sold

The total earned will be:
4x (for hot dogs) + 2y (for pretzels) = $800

Given that they have a total of 300 hot dogs and pretzels:
x + y = 300

Solving these two equations simultaneously:
4x + 2y = 800
x + y = 300

Multiply the second equation by 2 to align the coefficients of y:
2x + 2y = 600

Subtract the second equation from the first:
2x = 200
x = 100

Now that we know x = 100, plug this back into the second equation to solve for y:
100 + y = 300
y = 200

Therefore, the boosters need to sell 100 hot dogs and 200 pretzels in order to reach their goal of $800. So the correct answer is: 100 hot dogs and 200 pretzels.
