a daily newspaper had 12,125 subscribers when it began publication. five years later it has 10,100 subscribers. what is the average yearly rate of change in the number of subscribers for the five year period?
what is (12125-10100)/(12125*5)?
change that to percent by multiplying it by 100
To find the average yearly rate of change in the number of subscribers for the five-year period, you need to calculate the total change in the number of subscribers and divide it by the number of years.
First, subtract the number of subscribers at the start from the number of subscribers at the end to find the total change:
Total Change = Number of Subscribers at the End - Number of Subscribers at the Start
Total Change = 10,100 subscribers - 12,125 subscribers
Total Change = -2,025 subscribers
Next, divide the total change by the number of years to get the average yearly rate of change:
Average Yearly Rate of Change = Total Change / Number of Years
Average Yearly Rate of Change = -2,025 subscribers / 5 years
Average Yearly Rate of Change = -405 subscribers per year
Therefore, the average yearly rate of change in the number of subscribers for the five-year period is a decrease of 405 subscribers per year.
