1) 9 cups
2) 5 cups
3) 3 cups
4) 7 cups

Answer 1

After Mrs. Gatting makes 4 batches of a recipe using 2 fluid ounces of olive oil per batch, she will have 15 cups of olive oil left in the can, as she used a total of 1 cup for the batches from the initial 1 gallon she had.

Step-by-step explanation:

The question asks how many cups of olive oil are left in the can after Mrs. Gatting makes 4 batches of a recipe, with each batch requiring 2 fluid ounces of olive oil. To solve this problem, we need to convert fluid ounces to cups and subtract the quantity used from the total amount initially available.

1. First, determine the total amount of olive oil used: 4 batches × 2 fluid ounces per batch = 8 fluid ounces total.
2. Convert the fluid ounces used to cups using the unit equivalence: 1 cup = 8 fluid ounces.
   So, 8 fluid ounces = 1 cup.
3. Subtract the amount of olive oil used from the starting quantity. Mrs. Gatting started with 1 gallon of olive oil, which is equivalent to 16 cups (since 1 gallon = 4 quarts, and 1 quart = 4 cups).

Therefore, there are 15 cups of olive oil left in the can.
