Algebra.Com's Answer #502239 by JulietG(1812)![]() ![]() You can put this solution on YOUR website! What you're looking for is the point at which Company B charges $89 (the same as Company A). \n" ); document.write( "B = 75 + .7x \n" ); document.write( "Set it against the Company A value \n" ); document.write( "89 = 74 + .7x \n" ); document.write( "Subtract 74 from each side \n" ); document.write( "15 = .7x \n" ); document.write( "Multiply each side by .7 \n" ); document.write( "10.5 = x (or in this case, M) \n" ); document.write( "A charges less than B when M >10.5 \n" ); document.write( " \n" ); document.write( " |
