Pat, the range is simply the highest value in a given set minues the lowest so for this problem you have to put the numbers in order from least to greatest than take the higest number and subtract in from the lowest. In this case that is where the 49 comes from. Which of this choices has a difference of 49 between the highest and lowest number? If am correct the answer is d

Subtract the smallest number in each set from the largest number to find the range.
Example: 92  45 = 47 
it is d because 99(highest #)50(lowest #)=49.
