You don't say whether you want simple interest or compound interest. I will assume you want the latter.
A = Compound Amount = P(1+0.04)^3
= $34100(1+0.04)^3 = $38357.86 (answer)
Answer: Option C
Step-by-step explanation:
Given the quadratic equation
, substitute
:

In this case, to find the solutions of the given quadratic equation, you must factor out the variable "x". Then:

Therefore, you get that the solutions of this equation are the following:

Then, the answer is:
This matches with the option C.
The first I think is 4 units square and the second is 21 units square
