Answer:

Top to Bottom:

  • 12% growth
  • 12% decay
  • 20% decay
  • 22% growth

Step-by-step explanation:

Subtract 1 from the number in parentheses (the base of the exponential factor). Multiply the result by 100%. This gives you the percentage growth (positive) or decay (negative).

  (1.12 -1)×100% = +12% (growth)

  (0.88 -1)×100% = -12% (decay)

  (0.80 -1)×100% = -20% (decay)

  (1.22 -1)×100% = +22% (growth)

_____

The sign of the change (+ or -) and the description (growth or decay) convey the same information. It can be confusing to say -12% decay. Rather, the decay is 12%, or the growth is -12%. Above, we tried to indicate that positive is growth and negative is decay. We're not trying to say that the decay is -12%.
