Schererville has a population of 70,000 people. Schererville starts to experience a
population decline. Its population decreases by 4% each year.
1. Write an exponential function rule for both.
2. Create a Table and Graph to model the population of both cities for year
2010 to 2020.
3. During what year will the population of Danville first exceed that of
Schererville? Explain.
4. Create a table and graph to model the difference in population for both

thats the first half

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
