  3. 3.6 NOTES EXCITING TOPICS: Compounding interest annually Compounding interest continuously EXAMPLES!!!

  4. Interest Compounded "k" times per year P= amount invested (principal amount) r = rate (as a decimal) n= number of times per year it is compounded t = number of years A= amount in account after "t" years

  5. Interest Compounded Continuously P= amount invested r = rate (as a decimal) t = number of years A= amount in account after "t" years

  6. EXAMPLES :) Find the amount A compounded annually using the given informationP= $3200 r = 8% n = 1 t = 4

  7. MORE EXAMPLES! Find the amount A compounded annually using the given information P= $15,500 r = 9.5% n = 1 t = 12 15,500

  8. GUESS WHAT? EXAMPLES!! Find the amount A, compounded continuously, using the given informationP= $3,350 r = 6.2% t = 8

  9. LAST BUT NOT LEAST... EXAMPLES! Find the amount A, compounded continuously, using the given information P= $8,875 r = 4.4% t = 25

  10. WORD PROBLEMS!! YAY!!! If Amanda invests $8,000 into a dream vacation account to Madagascar to see the meerkats, with a 9% interest rate compounded monthly, how long will it take until this single payment has grown in her account to $16,000? P = 8,000 r = 9% A= 16,000 t = ?

  11. MORE WORD PROBLEMS!! At what interest rate, compounded continuously, would $3000 grow to $300,000 in 25 years? P= $3000 r = ? t = 25 A=$300,000
