Answer: 3 quarts of coffee.
Step-by-step explanation:
A coffee mug can take 16 fluid ounces.
Annie needs to fill up 6 mugs so the total ounces needed for 6 mugs would be:
= 16 * 6
= 96 fluid ounces
As the answer needs to be in quarts, convert the above.
1 quart = 32 fluid ounces
96 fluid ounces = 96/32
= 3 quarts
