Algebra.Com's Answer #818464 by Theo(13342)![]() ![]() You can put this solution on YOUR website! let T = the total number of stars in the bottle. \n" ); document.write( "let B = the number of stars that bobby made. \n" ); document.write( "let E = the number of stars that edward made. \n" ); document.write( "let K = the number of stars that kelvin made.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "The number of paper stars Bobby made was 21 more than 1/4 the total number of paper stars in the bottle. \n" ); document.write( "the equation for that is B = 1/4 * T + 21.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "let R1 equal the remaining stars in the bottle after subtracting what bobby made. \n" ); document.write( "the equation for that is R1 = T - B. \n" ); document.write( "since B = 1/4 * T + 21 then the equation becomes: \n" ); document.write( "R1 = T - (1/4 * T + 21) which becomes: \n" ); document.write( "R1 = 3/4 * T - 21.\r \n" );
