The New York Times Doesn’t Know Any Math Teachers
- jmount 12y agoI like this NTYP misses a literally perfect work problem (you can solve for the two different sales quantities from the numbers quoted in the article). But this is pretty compatible with the NYT 2012 position that you don't need algebra.

- jmount 12y agoNTYP -> NYT, work->word (sorry was on my way out the door when I posted that)
- coolswan 12y agoImpressive that over 80% of sales was online
- chrismcb 12y agoConsidering 100% of the sales were online! why is that impressive?

- nigwil_ 12y agoI think the solutions offered are incomplete, that is there is insufficient data in the NYT story to indicate the proportion of rentals to sales. The solutions offered have simply chosen one solution out of many. The solution needs to be parameterised, and that parameter is unknown (at this point).
