Answer:
24 fossil kits.
Explanation:
Given,
The number of fossil kits = 30,
the number of samples each has = 8,
So, the total samples = number of fossil kits × the number of samples contained by each kit
= 30 × 8
= 240,
Let x be the number fossil kits with 10 samples each,
Total samples = 10x
According to the question,
10x = 240

Hence, there would be 24 fossil kits with 10 samples each.
