ANSWER
to the nearest hundredth.
EXPLANATION
We have the equation,

Which can be rewritten as

The question demands the use of the quadratic formula.
Comparing this to the general quadratic equation;


The quadratic formula is given by;

We now substitute all the values in to the formula;

We simplify to obtain;


We now split the plus or minus sign to obtain;

This implies that;

Or

This will evaluate to;

Hence, the positive solution rounded to the nearest hundredth is

<em>Ohhh, interest problems. I haven't done an equation like this in a long time, but I will attempt.</em>
<em>I would say that the answer is the 2nd option. The equation is i = (5200)(0.06)(2.5).</em>
<em>The traditional interest formula is I = (P)(R)(N).</em>
<em>P = the original amount of money given</em>
<em>R = interest rate</em>
<em>N = the amount of time</em>
