Answer 1

To find the unit price for each option, we need to divide the total price by the number of ounces.

1. 48 ounces for $4.50: \[ \text{Unit Price} = \frac{4.50}{48} \approx 0.09375 \text{ dollars per ounce} \]

2. 64 ounces for $3: \[ \text{Unit Price} = \frac{3}{64} \approx 0.046875 \text{ dollars per ounce} \]

3. 128 ounces for $7: \[ \text{Unit Price} = \frac{7}{128} \approx 0.0546875 \text{ dollars per ounce} \]

Now let's compare the unit prices:

• 48 ounces: $0.09375 per ounce
• 64 ounces: $0.046875 per ounce
• 128 ounces: $0.0546875 per ounce

The 64-ounce option has the lowest unit price of approximately $0.04688 per ounce.

Therefore, the answer is:

64 ounces.
