The answer is 2.45 x 10^5. 

7 x 3.5 = 24.5

Move the decimal place over to the left until you have a number between 1 and 9 before the decimal point.

Add the number of times you moved the decimal point to the exponent (The 4 in the original equation).

2.45 x 10^5.

I hope this helps!

Find the accumulated amount of the annuity. (Round your answer to the nearest cent.) $1000 monthly at 4.6% for 20 years.
pantera1 [17]

Answer:

Accumulated amount will be $2504.90.

Step-by-step explanation:

Formula that represents the accumulated amount after t years is

A = A_{0}(1+\frac{r}{n})^{nt}

Where A = Accumulated amount

A_{0} = Initial amount

r = rate of interest

n = number of times initial amount compounded in a year

t = duration of investment in years

Now the values given in this question are

A_{0} = $1000

n = 12

r = 4.6% = 0.046

t = 20 years

By putting values in the formula

A = 1000(1+\frac{0.046}{12})^{240}

  = 1000(1+0.003833)^{240}

  = 1000(1.003833)^{240}

  = 1000×2.50488

  = 2504.88 ≈ $2504.90

Therefore, accumulated amount will be $2504.90.
