To find the unit rate for each brand of tomatoes, we need to determine the cost per ounce for each brand.

Brand A:

  • Size: 8 ounces
  • Cost: 2 dollars and 99 cents (which can be converted to dollars: 2.99)

To find the cost per ounce for Brand A, we do the following calculation:

\[ \text{Cost per ounce} = \frac{\text{Total Cost}}{\text{Total Ounces}} = \frac{2.99}{8} \]

Calculating this gives:

\[ \frac{2.99}{8} = 0.37375 \text{ dollars per ounce} \]

Rounding to the nearest cent:

\[ 0.37375 \approx 0.37 \text{ dollars per ounce} \]

Brand B:

  • Size: 16 ounces
  • Cost: 4 dollars and 99 cents (which can be converted to dollars: 4.99)

To find the cost per ounce for Brand B, we do the following calculation:

\[ \text{Cost per ounce} = \frac{4.99}{16} \]

Calculating this gives:

\[ \frac{4.99}{16} = 0.311875 \text{ dollars per ounce} \]

Rounding to the nearest cent:

\[ 0.311875 \approx 0.31 \text{ dollars per ounce} \]

Summary of unit costs:

  • Brand A costs $0.37 per ounce.
  • Brand B costs $0.31 per ounce.
