Answer 1

To determine which size of ice cream has the lower unit price, we need to calculate the price per ounce for each size.

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

2. 64 ounces for $3: \[ \text{Unit price} = \frac{3.00}{64} = 0.046875 \text{ dollars per ounce} \]

3. 128 ounces for $7: \[ \text{Unit price} = \frac{7.00}{128} = 0.0546875 \text{ dollars per ounce} \]

Now we compare the unit prices:

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

The size with the lowest unit price is 64 ounces.
