Answer:
B
Step-by-step explanation:
According to the Factor Theorem, if (<em>x</em> - <em>a</em>) is a factor (where <em>a</em> is a zero) of the polynomial P(x), then P(a) must equal zero.
Our zeros are 4, √7, and - √7. Hence, when evaluating P(4), P(√7), and P(-√7), all must evaluate to zero.
Testing each choice, we can see that only choice B is true. That is:

In conclusion, our answer is B.
we know that
The simple interest formula is equal to

where
I is the simple interest
P is the principal ( the amount borrowed or deposited)
r is the interest rate
t is the time
in this problem we have

Substitute the values in the formula above


therefore
<u>the answer is</u>
The amount of interest earned is equal to 
A.40,48 is the right answer
