Give the step-by-step reasoning process and then the final answer. There are three buckets of seeds labeled A, B, and C with 100 seeds. There are ten more seeds in bucket A than in bucket B, and bucket B has 30 seeds. How many seeds are in bucket C?
Bucket A has 10 more seeds than bucket B: so there are 10 seeds + 30 seeds = 40 seeds in bucket A. Bucket A and bucket B have 40 seeds + 30 seeds = 70 seeds together. If there are 100 seeds in all the buckets, then bucket C has 100 seeds - 70 seeds = 30 seeds.
The final answer: 30.
