Nick uses 1/4 cup of vinegar for every 1 cup of olive oil when making salad dressing. Using this recipe, how much vinegar would he need to make salad dressing with 12 cups of olive oil?

3 cups of vinegar

Step-by-step explanation:

∵ Nick uses the amount of vinegar for every 1 cup of olive oil = cup

∴ He will need the amount of vinegar for 12 cups of olive oil = cups

                                                                                                 = 3 cups

Therefore, Nick will need 3 cups of vinegar to make salad dressing.

Point A

Step-by-step explanation:

The question is asking for a drop in 3 degrees. That means whatever point we start on, we subtract 3 from it. We start on 0, so 0-3=-3. That is point A.
