Answer:
The range in shelter A is 22, and the range in shelter B is 18.
Explanation:
Okay so basically, the range is the difference between the smallest number and the greatest number.
The smallest weight for shelter a is 8. The largest weight is 30.
30-8= 22.
Same thing for the other shelter. The smallest weight is 10, and the largest weight is 28. 28-10= 18.
