Algebra.Com's Answer #597586 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! 0.25 + 0.10 (x-4) <+ 2.10; x= an integer number of minutes. Need to subtract 4, because the first four are paid for with the 0.25 charge. Need an integer, because fractional minutes count as a full minute.\r \n" ); document.write( "\n" ); document.write( "0.25+ 0.10x -0.40 <=2.10 \n" ); document.write( "-0.15 +0.10 x<=2.10 \n" ); document.write( "0.10x <=2.25 This is an alternative. \n" ); document.write( " |
