2. The amount of an ordinary $9000.00 annuity for 3 years at 12 percent compounded quarterly is _______? Show work.

larisa [96]

Answer:

The amount after three years is $12831.8

Step-by-step explanation:

* Lets revise the compound interest

- The formula for compound interest is A = P (1 + r/n)^(nt)

Where:

# A = the value of the investment with interest

# P = the initial investment amount

# r = the annual interest rate (decimal)

# n = the number of times that interest is compounded per unit t

# t = the time the money is invested

* Now lets solve the problem

∵ The initial amount is $9000

∴ P = $9000

∵ The rate is 12%

∴ r = 12/100 = 0.12

∵ The interest is compound quarterly

∴ n = 4

∵ The money invested for 3 years

∴ t = 3

∵ A = P (1 + r/n)^(nt)

∴ A = 9000(1 + 0.12/4)^(4×3)

∴ A = 9000(1 + 0.03)^12

∴ A = 9000(1.03)^12 = $12831.8

Paddy and Anna each invest $2000 for 5 years.

Serga [27]

Answer: r= 1.22

Step-by-step explanation:

Formula for amount with simple interest = $P(1+rt)$

, where

P= principal value , r= rate of interest , t = time.

Given: P= $2000, t= 5 years, r= 1.25% = 0.0125

$A=2000(1+0.0125\times5)\\\\=2000(1.0625)=2125$

Formula to compute compound amount : $P(1+r)^t$

$=2000(1+r)^5$

When both have same worth then

$2000(1+r)^5=2125\\\\\\ (1+r)^5=\dfrac{2125}{2000}\\\\\\ (1+r)^5=1.0625$

taking log on both sides , we get

$5\ln (1+r)=\ln 1.0625\\\\\\ 5\ln (1+r)=0.0606246\\\\\\ \ln (1+r)=0.012125\\\\\\ 1+r=e^{0.005266}\\\\\\ 1+r=1.0122\\\\ r=0.0122\\\\ \\ r=1.22\%$

Hence, Value of r= 1.22
