Algebra.Com's Answer #35418 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! It's the amt she spends that has to be all the same digits, isn't it? \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "All we have to do is find out what multiple of 28 has all the same digits. \n" ); document.write( ": \n" ); document.write( "Acually between 100 and 1 million there is not that many. We know the number has to be even, no zeros obviously. Get a calculator and start with 222/28, then 444/28, etc. I got to 444444 and found that 28 goes evenly into it, 15873 times so this many tiles cost $4,444.44. \n" ); document.write( ": \n" ); document.write( " \n" ); document.write( " |
