Answer 1

Let \( h \) represent the number of hot dogs sold and \( p \) represent the number of pretzels sold. We are given two equations based on the problem:

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

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

Now we can solve this system of equations.

First, we can simplify the second equation. Divide the entire equation by 2: \[ 2h + p = 400 \]

Now we have the simpler set of equations:

1. \( h + p = 300 \) (1)
2. \( 2h + p = 400 \) (2)

Next, we'll solve for \( p \) in equation (1): \[ p = 300 - h \]

Now we can substitute this expression for \( p \) into equation (2): \[ 2h + (300 - h) = 400 \] \[ 2h + 300 - h = 400 \] \[ h + 300 = 400 \] \[ h = 400 - 300 \] \[ h = 100 \]

Now that we have \( h \), we can find \( p \): \[ p = 300 - h = 300 - 100 = 200 \]

So, the boosters need to sell:

• 100 hot dogs and 200 pretzels.

Looking at the responses, the correct one is: 100 hot dogs and 200 pretzels.
