To solve for range, subtract the highest and the lowest number in the set of data. In this case the highest and smallest number in data 56, 81, 54, 47, 45, 94 is 45 and 94. The original range of the set is 49. To make the range 55, Subtract the desired range to the original range. Then, add the difference to the highest number(94) or subtract the difference to the lowest number(45).
= 55-49 = 6.
Highest number(94) plus the difference(6)
=94 +6 = 100.
Lowest number(45) minus the difference(6)
= 45 - 6 = 39.
The numbers that can be added to the data so that the range of the data will be 55 are 100 and 39.
