Final answer:
The extra-large bucket will hold 80 quarts.
Step-by-step explanation:
The extra-large bucket will hold 80 quarts.
To find the number of quarts the extra-large bucket holds, we can observe the pattern of the sizes of the buckets. Starting from the tiny bucket, each subsequent bucket doubles in size. So, if the small bucket holds 10 quarts, the medium bucket holds 20 quarts, and the large bucket holds 40 quarts, the extra-large bucket will hold 40 x 2 = 80 quarts.
