Question 53086: My daughter got this word problem for school and it sounds pretty simple to me but I have tried everything and I am horrible at math so I need a little help before I throw my calculator out the window! Here is it
Linae went shopping for Kou-jong tiles at the local toy shop the other day. The kou-jong tiles were on sale for only 28 cents each.
However, she got it in her head that, for good luck, the total amount of money she must spend must be a number where all of the digits are the same.
With that in mind, what is the minimum number of tiles she must buy?

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?

All we have to do is find out what multiple of 28 has all the same digits.

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.
