EXCITING TOPICS:

Compounding interest annually

Compounding interest continuously

EXAMPLES!!!

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 invested

r = rate (as a decimal)

t = number of years

A= amount in account after "t" years

Find the amount A compounded annually

using 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 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 = ?

At what interest rate, compounded continuously, would $3000 grow to $300,000 in 25 years?

P= $3000 r = ? t = 25 A=$300,000
