Answer:
The growth factor for the annual rate of change of 15% is 1.15.
The decay factor for the annual rate of change of -30% is 0.7.
The decay factor for the annual rate of change of -70% is 0.3.
The growth factor for the annual rate of change of 100% is 2.
Explanation:
Growth or decay factor:
The growth factor is 1 + r, r as a decimal.
The decay factor is 1 - r, r as a decimal.
For the annual rate of change, find the corresponding growth or decay factor: +15%
r = 0.15, so 1 + 0.15 = 1.15.
The growth factor for the annual rate of change of 15% is 1.15.
For the annual rate of change, find the corresponding growth or decay factor: -30%
r = -0.3, so 1 - 0.3 = 0.7.
The decay factor for the annual rate of change of -30% is 0.7.
For the annual rate of change, find the corresponding growth or decay factor: -70%
r = -0.7, so 1 - 0.7 = 0.3.
The decay factor for the annual rate of change of -70% is 0.3.
For the annual rate of change, find the corresponding growth or decay factor: +100%
r = 1, so 1 + 1 = 2.
The growth factor for the annual rate of change of 100% is 2.
