EXCITING TOPICS:
Compounding interest annuallyCompounding interest continuouslyEXAMPLES!!!
P= amount invested (principal amount)r = rate (as a decimal)n= number of times per year it is compoundedt = number of yearsA= amount in account after "t" years
P= amount investedr = rate (as a decimal)t = number of yearsA= amount in account after "t" years
Find the amount A compounded annuallyusing the given information
P= $3200 r = 8% n = 1 t = 4
Find the amount A compounded annuallyusing the given information
P= $15,500 r = 9.5% n = 1 t = 12
15,500
Find the amount A, compounded continuously,
using the given information
P= $3,350 r = 6.2% t = 8
Find the amount A, compounded continuously,using the given information
P= $8,875 r = 4.4% t = 25
If Amanda invests $8,000 into a dream vacation account toMadagascar to see the meerkats, with a 9% interest ratecompounded 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 = ?
At what interest rate, compounded continuously, would $3000 grow to $300,000 in 25 years?
P= $3000 r = ? t = 25 A=$300,000
