It will increase.
It will decrease.
It will stay the same.

Answer 1

Your correct answer is A: it will increase.

Hope this helps. :)

Answer 2

Since the range of a set of numbers is based entirely on the smallest number and the largest number (the largest number minus the smallest), and since 12 is the smallest number, the value of the range will decrease.
