A sample of 350 grams of radioactive substance decays according to the function A(t) = 350e^-0.044t where t is the time in years. How much of the substance will be left in the sample after 10 years? Round to the nearest whole gram
---------------------------------------
A(10) = 350*e^(-0.044*10)
A(10) = 350*0.6440
A(10) = 225.41
Rounded down: 225 grams
