Standard coffee mug has a capacity of 16 fluid ounces.

If Annie needs to fill 48 mugs with coffee, how many total quarts of coffee does she need?

24 quarts

Step-by-step explanation:

48 mugs of coffee is equal to the capacity of 1 coffee mug multiplied by 48 (16x48=768) This gives you the capacity of the 48 mugs in fluid ounces. You then need to how many ounces are in a quart (1 quart = 32 fluid ounces). You then divide the capacity of the 48 mugs by 32 to find how many quarts of coffee she needs. (768/32=24)
