Chapter 10, Problem 39TS

The formula for the half-life can be expressed as $A=A_0{\left(1/2\right)}^{t/h}$ where $A_0$ is initial amount, $A$ is final amount, $t$ is duration of time, and $h$ is the half-life. If in 1750, Benjamin Franklin buried $25\text{kg}$ of carbon-14 in his backyard, how much of this carbon-14 would be found in 2150? Use calculator with $y^x$ exponential function.
