For the annual rate of change, find the corresponding growth or decay factor: +15% For the annual rate of change, find the corresponding growth or decay factor: -30%
For the annual rate of change, find the corresponding growth or decay factor: -70%
For the annual rate of change, find the corresponding growth or decay factor: +100%

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.

Step-by-step 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.

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.
