Answer 1

To determine which theater offers the best buy for popcorn, we need to calculate the price per ounce for each theater. We can do this by dividing the price by the number of ounces.

1. CinePlex:

   • Price: $8.25
   • Ounces: 100
   • Price per ounce: \( \frac{8.25}{100} = 0.0825 \) (or 8.25 cents per ounce)

2. Mr. Movie:

   • Price: $7.00
   • Ounces: 96
   • Price per ounce: \( \frac{7.00}{96} \approx 0.0729 \) (or about 7.29 cents per ounce)

3. Stadium Cinema:

   • Price: $6.50
   • Ounces: 112
   • Price per ounce: \( \frac{6.50}{112} \approx 0.0580 \) (or about 5.80 cents per ounce)

4. TheaterMania:

   • Price: $7.50
   • Ounces: 136
   • Price per ounce: \( \frac{7.50}{136} \approx 0.0551 \) (or about 5.51 cents per ounce)

Now we can summarize the price per ounce for each theater:

• CinePlex: 8.25 cents/ounce
• Mr. Movie: 7.29 cents/ounce
• Stadium Cinema: 5.80 cents/ounce
• TheaterMania: 5.51 cents/ounce

Comparing these prices, we can see that TheaterMania has the lowest price per ounce at approximately 5.51 cents, making it the best buy for popcorn.
