50 hot dogs and 250 pretzels

Answer 1

To solve this problem, we can set up a system of equations. Let's say the boosters sell x hot dogs and y pretzels.

The income from selling hotdogs is 4x, and the income from selling pretzels is 2y. The total income should be $800, so we can write the equation:

4x + 2y = 800

We also know that the boosters have 300 hot dogs and pretzels in stock, so the total number of items sold should be x + y = 300.

To solve this system of equations, we can use substitution or elimination.

Let's use substitution. Solve the second equation for x: x = 300 - y.

Substitute this expression for x in the first equation:

4(300 - y) + 2y = 800

Distribute and simplify:

1200 - 4y + 2y = 800

Combine like terms:

-2y = 800 - 1200

-2y = -400

Divide by -2:

y = 200

Now substitute this value for y in the second equation:

x + 200 = 300

Subtract 200 from both sides:

x = 100

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

So the answer is 100 hot dogs and 200 pretzels.
