Answer:

8(4+x)= 64

(8*4)+(8*x)= 64

8x+32= 64

8x= 64-32

8x= 32

x= 32/8

x= 4

32+8x=64
Subtract 32 from both sides...
8x=32
Divide 32 by 8...
X=4

Find the annual interest rate. Round your answer to the nearest hundredth of a percent. I=$160.67, P=$2000, t=8 monthsI=$160.67,

Keith_Richards [23]

Answer:

The annual interest rate is 12.05%.

Step-by-step explanation:

The simple interest is given by the formula:

$I=\dfrac{P\times R\times T}{100}$

Where I denotes interest.

P denotes the principal amount.

R denotes the rate of interest

and T denotes the time period.

I=$160.67, P=$2000, t=8 months=8/12 years (Since 12 months=1 year so 1 month=1/12 year)

$160.67=\dfrac{2000\times R \times \dfrac{8}{12}}{100}\\\\R=12.05%$

Hence, the annual interest rate is 12.05%.

Answer:

d 20.4 years

Step-by-step explanation:

The equation is

A = Pe ^(rt)

We know that r = .034

We want the money to double so A = 2P

Substitute in

2P = P e ^(.034t)

Divide by P

2P/P = P/P e ^(.034t)

2 = e^ (.034t)

Take the natural log on each side

ln (2) = ln(e^ (.034t))

ln (2) = .034t

Divide by .034

ln (2) /.034 = .034t/.034

ln (2)/.034 = t

20.3867 =t
