Answer:

$11,028.68

Step-by-step explanation:

As we all know, the simple interest formula is as follows:

[tex]P(1+rt)[/tex]

Wherein:

P = Principal amount

r = rate (in percentage so, rate/100)

t = time (in years)

Hence, when we substitute in these values,

[tex]8255(1+(4.2/100)*8)[/tex]

= $11,028,68

it will be 4.2/100 as it is percentage form.

B. 11,028.68

I = PRT where I = interest earned, P = principal/money deposited, R = interest rate in decimal form, and T = time in years

Plugging in what we know:
I = (8255)(0.042)(8)
I = 2773.68

Add that to the principal
8,255 + 2,773.68 = 11,028.68
