Question

A 2-column table with 2 rows. Column 1 is labeled Brand A with entries 8 ounces, 2 dollars and 99 cents. Column 2 is labeled brand B with entries 16 ounces, 4 dollars and 99 cents.

Find the unit rate for each brand. Round to the nearest cent (hundredth).

Brand A costs
per ounce.
Brand B costs
per ounce.

Answer 1

To find the unit rate for each brand, we need to calculate the cost per ounce for both Brand A and Brand B.

Brand A:

• Amount: 8 ounces
• Cost: $2.99

To find the cost per ounce: \[ \text{Cost per ounce} = \frac{\text{Cost}}{\text{Amount}} = \frac{2.99}{8} \] Calculating this: \[ \frac{2.99}{8} \approx 0.37375 \] Rounding to the nearest cent: \[ \text{Cost per ounce for Brand A} \approx 0.37 \text{ dollars} \]

Brand B:

• Amount: 16 ounces
• Cost: $4.99

To find the cost per ounce: \[ \text{Cost per ounce} = \frac{\text{Cost}}{\text{Amount}} = \frac{4.99}{16} \] Calculating this: \[ \frac{4.99}{16} \approx 0.311875 \] Rounding to the nearest cent: \[ \text{Cost per ounce for Brand B} \approx 0.31 \text{ dollars} \]

Summary:

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