Multiple Choice

Solve the problem.
-A sample of $300 \mathrm {~g}$ of lead-210 decays to polonium-210 according to the function given by $\mathrm { A } ( \mathrm { t } ) = 300 \mathrm { e } ^ { - 0.032 \mathrm { t } }$ , where $\mathrm { t }$ is time in years. What is the amount of the sample after 60 years (to the nearest g) ?

A) $44 \mathrm {~g}$
B) $2046 \mathrm {~g}$
C) $230 \mathrm {~g}$
D) $32 \mathrm {~g}$
