Answer 1

Looking at the unit prices, the Kernels Popcorn is the best buy because it has the lowest cost per ounce at $0.46.

Step-by-step explanation:

Sure, let’s calculate the unit rate (cost per ounce) for each package:

Part A:

Pop-A-Lot: $4.32 / 9 ounces = $0.48 per ounce

Pop Kornz: $3.00 / 5 ounces = $0.60 per ounce

Pop-arazzi: $8.25 / 15 ounces = $0.55 per ounce

Kernels Popcorn: $3.22 / 7 ounces = $0.46 per ounce

Part B:

The unit rates calculated in Part A represent the cost of each ounce of popcorn for each brand. It helps us understand how much we are paying for each ounce of popcorn.

Part C:

Looking at the unit prices, the Kernels Popcorn is the best buy because it has the lowest cost per ounce at $0.46. This means you get more popcorn for your money compared to the other brands.

Answer 2

To calculate the corresponding unit rate for each package, divide the cost by the size of each package. The unit rates represent the cost of 1 ounce of popcorn for each package, allowing for comparison. The package with the lowest unit rate is the best buy.

Step-by-step explanation:

Part A: To calculate the corresponding unit rate for each package, we need to divide the cost by the size of each package.

For Pop-A-Lot Pop Kornz, the unit rate is $4.32 / 9 ounces = $0.48 per ounce.

For Pop-arazzi Kernels Popcorn, the unit rate is $8.25 / 15 ounces = $0.55 per ounce.

For Kernels Popcorn, the unit rate is $3.22 / 7 ounces = $0.46 per ounce.

Therefore, the unit rates for each package are:

• Pop-A-Lot Pop Kornz: $0.48 per ounce
• Pop-arazzi Kernels Popcorn: $0.55 per ounce
• Kernels Popcorn: $0.46 per ounce

Part B: The unit rates found in Part A represent the cost of 1 ounce of popcorn for each package. It allows us to compare the prices of different-sized packages and determine which one is more affordable based on the price per ounce.

Part C: The best buy would be the package with the lowest unit rate, which is Kernels Popcorn at $0.46 per ounce.
