A scientist measures the initial amount of Carbon-14 in a substance to be 25 grams.
The relationship between A, the amount of Carbon-14 remaining in that substance, in grams, and t, the elapsed
time, in years since the initial measurement is modeled by the following equation.
A = 25e -0.00012
In how many years will the substance contain exactly 20 grams(g) of Carbon-1
Give an exact answer expressed as a natural logarithm.
