New value old value ABS old value. Increasing 1 five times gives you 5 however anything multiplied by zero is always zero so starting at zero and increasing it will never give you 19. And sometimes the actual stress value may be zero.
I need to calculate the percent to goal when injuries exist exceed the goal.
No money was made in the first period so y1 is 0 the formula divides by 0 which is mathematically meaningless. Just wanted to add that when you increase something by multiplication which is implied in the original question you need numbers bigger than zero. When P is actually zero then the concept of percentage change has no meaning. Y2 - y1y1 x 100 percent change.
