The initial investment = $250
<span>annual simple interest rate of 3% = 0.03
</span>
Let the number of years = n
the annual increase = 0.03 * 250
At the beginning of year 1 ⇒ n = 1 ⇒⇒⇒ A(1) = 250 + 0 * 250 * 0.03 = 250
At the beginning of year 2 ⇒ n = 2 ⇒⇒⇒ A(2) = 250 + 1 * 250 * 0.03
At the beginning of year 3 ⇒ n = 3 ⇒⇒⇒ A(2) = 250 + 2 * 250 * 0.03
and so on .......
∴ <span>The formula that can be used to find the account’s balance at the beginning of year n is:
</span>
A(n) = 250 + (n-1)(0.03 • 250)
<span>At the beginning of year 14 ⇒ n = 14 ⇒ substitute with n at A(n)</span>
∴ A(14) = 250 + (14-1)(0.03*250) = 347.5
So, the correct option is <span>D.A(n) = 250 + (n – 1)(0.03 • 250); $347.50

Answer:
A. 12 centimeters B. 4 centimeters C. 20 centimeters
Step-by-step explanation:
To find area you need to do the Height time the Length.
For A it is 3x4
For B it is 4x1
And for C it is 4x5
You get this equation by multiplying the amount of squares that the Height and Length measured!
Hope this helped!

Answer:
$2954.91 end of year eight
Step-by-step explanation:
2000 x 1.05^8 = 2000 x 1.04775 = $2954.91
Proof:
2000 x 1.05 = 2100 end of year one
2100 x 1.05 = 2205 end of year two
2205 x 1.05 = 2315.25 end of year three
2315.25 x 1.05 = 2431.01 end of year four
2431.01 x 1.05 = 2552.56 end of year five
2552.56 x 1.05 = 2680.19 end of year six
2680.19 x 1.05 = 2814.20 end of year seven
2814.20 x 1.05 = $2954.91 end of year eight
