The amount of the substance (At) at any time t is calculated through the equation,
At = (A0)(e^-kt)
where A0 is the initial amount and k is constant.
For the half-life,
ln (At / A0) = ln 0.5 = -k(5270 years)
The value of k is 1.3153x10^-4 / year.
Substituting this value to the same equation, where At = 0.25A0
ln 0.25 = -(1.3153 x 10^-4)(t)
The value of t from this equation is 10540 years. The closest value to this is letter A.

Answer: $7.99</h3>
Explanation:
Pick any point listed and divide the y coordinate over the x coordinate.
The simplest choice is the point where x = 1
y/x = (7.99)/(1) = 7.99
Or we could say something like
y/x = (95.88)/(12) = 7.99
