Answer:

$18100

Explanation:

Range is the difference between the highest and the lowest value in a data set. To calculate the highest value in a data set, we simply add the range to the lowest value,

In data set for may, the lowest value was 4500 while the range was 15000. So, the highest value will be

  • Highest Value = lowest value + range

                        = 4500 + 15000   ⇒  $19500

Similarly, for June, the highest value will be,

  • Highest Value = 6100 + 16500   ⇒ $22600

When we combine both data sets for May and June,

  • The lowest value of combined data set is $4500
  • The highest value of combined data set is $22600

The range of the combined data set will be,

  • Range = 22600 - 4500 ⇒ $18100
