Question

If $10,000 is invested at x percent simple annual interest for n years, which of the following represents the total amount of interest, in dollars, that will be earned by this investment in the n years?
A. 10,000(x^n)B. 10,000(x/100)^nC. 10,000n(x/100)D. 10,000(1+x/100)^n E. 10,000n(1+x/100)

Answer 1

Answer: C. $10000n\dfrac{x}{100}$

Step-by-step explanation:

Given : The principal amount : P=$10,000

Rate of interest (in percent ) : x

Time period :  n years

The formula to calculate the simple interest is given by :-

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

$\Rightarrow\ S.I.=\dfrac{10000\times x\times n}{100}$

it can also be written as $\Rightarrow\ S.I.=10000n\dfrac{x}{100}$

Hence, C is the right option.
