Algebra.Com's Answer #20344 by Earlsdon(6294)![]() ![]() ![]() You can put this solution on YOUR website! Let x = the number that can be bought for $20.00 each, then (59-x) = the number that can be bought for $50.00 each. You can write: \n" ); document.write( "$20(x) + $50(59-x) = $2380 Simplify and solve for x. \n" ); document.write( "$20(x) + $2950 - $50x = $2380 \n" ); document.write( "-$30(x) + $2950 = $2380 Subtract $2950 from both sides. \n" ); document.write( "-$30(x) = -$570 Divide both sides by -$30. \n" ); document.write( "x = 19 \n" ); document.write( "59-x = 40\r \n" ); document.write( "\n" ); document.write( "19 can be bought at $20.00 each \n" ); document.write( "40 can be bought at $50.00 each. \n" ); document.write( " |
