Write a recursive rule that models the following situation: Samantha's hair was known to grow very rapidly. It began at a length of 6 in and grew at a rate of 14% a week.

• Next = Now + 0.14, starting at 6

• Next = Now + 14, starting at 6

• Next = Now* 1.14, starting at 6

• Next = Now + Now *14, starting at 6
