Answer 1

To determine which option is the best deal, we need to calculate the cost per ounce for each yogurt option.

1. $3.20 for 40 ounces: \[ \text{Cost per ounce} = \frac{3.20}{40} = 0.08 \text{ dollars per ounce} \]

2. $2.16 for 28 ounces: \[ \text{Cost per ounce} = \frac{2.16}{28} = 0.0771 \text{ dollars per ounce (approximately)} \]

3. $0.66 for 6 ounces: \[ \text{Cost per ounce} = \frac{0.66}{6} = 0.11 \text{ dollars per ounce} \]

Now, let’s summarize the cost per ounce for each option:

• $3.20 for 40 ounces: $0.08 per ounce
• $2.16 for 28 ounces: $0.0771 (approximately) per ounce
• $0.66 for 6 ounces: $0.11 per ounce
