There would be a 10% chance that they would have the same birthday
YOU JUST DO 28*7 and you get 196
1000+1500=2500 is how much she owes right now
If each hat is sold for 12.50, all you have to do is 2500/12.50=200
She needs to sell 20 hats to break even.

The correct answer should be 100 root 10, or around 316.23
