Answer:
39 fluid ounces OR 4.875 cups
Step-by-step explanation:
To solve this problem, we need to find out how many fluid ounces are in one cup.
1 cup = 8 fluid ounces
3 cups = 24 fluid ounces
15 fluid ounces + 3 cups = 15 fluid ounces + 24 fluid ounces = 39 fluid ounces
OR
1 fluid ounce = 0.125 cup
15 fluid ounces = 1.875 cup
15 fluid ounces + 3 cups = 1.875 cup + 3 cups = 4.875 cups
