Given:
For the annual rate of change of +70%, find the corresponding growth or decay factor.
For the annual rate of change of -75%, find the corresponding growth or decay factor.
Solution:
Since we are given the percentages, we can find the annual rate of changes by simply converting the percentage to decimals. In converting a percentage into decimal, divide the percentage by 100, hence in converting a decimal to percentage, multiply the percentage by 100.
= 70/100
= 0.70
= -75%/100
= -0.75
Final answer:
= 0.70
= - 0.75
