1. John wanted to start an organization to stop seal clubbing in Canada. At first, there were only 5 members, but the number grew at a rate of 27% every year. John hopes to reach a total of 30 members in two years. Will he reach his goal?

2. Exponential Growth Equation

3. P= 5 (because there are originally 5 members) r=.27 (because 27/100=.27) t= 1 (number of years) Add what is inside parentheses Raise that number to the amount of time (1 in this case) Multiply by 5

4. A few months have gone by and John’s organization has not improved the seal clubbing issue at all. The population that used to be about 45000 has decreased at the rate of 25% every 3 years. What will the population be in 3 years?

5. Exponential Decay Equation

6. A= 9900 (final number of seals) P= 45000 (original number of seals) t= 1 (one year) Subtract what is in parentheses Raise to the 3rd power Multiply by 45000
