If p(0)=100,p(0)=100,p(0)=100, then p(t)p(t)p(t) equals:AOption A. 600−500 et/2600 - 500\,{e^{t/2}}600−500et/2BOption B. 400−300 e−t/2400 - 300\,{e^{-t/2}}400−300e−t/2COption C. 400−300 et/2400 - 300\,{e^{t/2}}400−300et/2DOption D. 300−200 e−t/2300 - 200\,{e^{-t/2}}300−200e−t/2CheckSkip · show solution
