One type of uranium has radioactive decay rate of 0.5%. If 20 pounds of this uranium is available today, find how much will still remain after 30days.
\n" ); document.write( "----------------------------
\n" ); document.write( "A(t) = Ao (1-0.005)^t
\n" ); document.write( "A(30) = 20(0.995)^30
\n" ); document.write( "A(30) = 20*0.8604
\n" ); document.write( "A(30) = 17.208 lbs.
