Answer» (a) A= p(1+r/100)t 44100=p(1+5/100)2 44100=p(105/100)2 44100=p*105/100*105/100 44100*100*100=p*105*105 p=(44100*100*100)/105*105 p=40000 Then, POPULATION of a town 2 YEARS ago is 40000. Population after 1 YEAR, A=p(1+r/100)t A=44100(1+5/100)1 A=44100*105/100 A=46,305 So, the population after 1 year is 46,305. |
