You are running a concession stand at a baseball game.

Question

You are selling pizza slices and sodas.

Each pizza slice sells for $3.50 and each soda sells for $1.50.

At the end of the night, you made a total of $800.

You sold a total of 344 pizza slices and sodas combined.

You must report the number of pizza slices sold and the number of sodas sold.

What equations did you use to solve this, where P = the number of pizza slices sold and S = the number of sodas sold?

3.50P + S = 800 and P + 1.50S = 344
3.50P + S = 800 and P + 1.50S = 344

3.50S + 1.50P = 800 and P + S = 344
3.50S + 1.50P = 800 and P + S = 344

3.50P + 1.50S = 800 and P + S = 344
3.50P + 1.50S = 800 and P + S = 344

3.50S + 1.50P = 344 and P + S = 800

Answer 1

To solve the problem, let's define:

• \( P \) as the number of pizza slices sold
• \( S \) as the number of sodas sold

From the problem, we can derive the following equations:

1. The total revenue from pizza slices and sodas is $800:
   \[ 3.50P + 1.50S = 800 \]

2. The total number of items sold (pizza slices and sodas) combined is 344:
   \[ P + S = 344 \]

So, the correct equations to use are:

1. \( 3.50P + 1.50S = 800 \)
2. \( P + S = 344 \)

Thus, the correct answer is:
3.50P + 1.50S = 800 and P + S = 344
