If the cost of 1 ½ cup of dressing is $3.00, how much would the cost of 3 ½ oz be?

Solution:
1. Given:
- Cost of 1 ½ cups of dressing is USD3.00.
- 1 cup = 8 ounces. Therefore, 1 ½ cups = 12 ounces.

2. Determine the cost per ounce:
- Cost of 12 ounces = USD3.00.
- Cost per ounce = USD \\frac{3.00}{12} = USD0.25.

3. Calculate the cost for 3 ½ ounces:
- 3 ½ ounces = 3.5 ounces.
- Cost for 3.5 ounces = 3.5 \times USD0.25 = USD0.875.

4. Therefore, the cost of 3 ½ oz of dressing is USD0.875.
