-A sample of 1000 g of lead-210 decays to polonium-210 according to the function given by $\mathrm { A } ( \mathrm { t } ) = 1000 ( 2.718 ) ^ { - 0.032 t } ,$ where t is time in years. What is the amount of the sample, to the nearest gram, after 40 years?
A)3596 g
B)16 g
C)202 g
D)278 g

Solve the Problem A(t)=1000(2.718)−0.032t,\mathrm { A } ( \mathrm { t } ) = 1000 ( 2.718 ) ^ { - 0.032 t } ,A(t)=1000(2.718)−0.032t,

Solve the Problem $\mathrm { A } ( \mathrm { t } ) = 1000 ( 2.718 ) ^ { - 0.032 t } ,$
