Between 1980 and 1990 the population of Columbus grew 12%. \n" ); document.write( "a) Fill in the blank.. If the 1980 population was P, then the 1990 population was _______ my answer is P+(P*.12) \n" ); document.write( "1990 Population = 1.12P \n" ); document.write( "--------------------------- \n" ); document.write( "b) The 1990 Population was 632910. Write an equation and find the 1980 population \n" ); document.write( "1990 Pop = 1.12 (1980 Pop) \n" ); document.write( "632910 = 1.12 (1980 Pop) \n" ); document.write( "Divide both sides by 1.12 to get: \n" ); document.write( "1980 Pop = 632910/1.12 \n" ); document.write( "= 565098.21 \n" ); document.write( "You should round this out because you cannot have 0.21 persons. \n" ); document.write( "=565098 \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
