To find the number of years after which the value of the software is $190, substitute $190 for V in the equation and solve for t: $190 = -30t + 250. Rearranging the equation gives -30t = $190 - $250, which simplifies to -30t = -$60. Dividing both sides by -30 gives t = 2. Therefore, the value of the software is $190 after 2 years.
