hello ya im helping my son homework.regarding estimation to get reasonable range. Three classes collected aluminum cans for recycling .one class collected 42 cans,another collected 56 cans,and the third class collected 64 cans .what is a reasonable range of the number of cans the classes collected?

range means maximum minus minimum

so that is 42-64=?

im pretty sure this is what it is, if your son gets this wrong i am so so sorry

To find a reasonable range of the number of cans the classes collected, we need to determine the minimum and maximum values.

Step 1: Arrange the number of cans in ascending order:
42, 56, 64

Step 2: Determine the minimum value:
The minimum value is the smallest number, which in this case is 42.

Step 3: Determine the maximum value:
The maximum value is the largest number, which in this case is 64.

Step 4: Calculate the range:
The range is the difference between the maximum and minimum values.
Range = Maximum value - Minimum value = 64 - 42 = 22

Therefore, the reasonable range of the number of cans the three classes collected is from 42 to 64 cans.
