Question 1042275
If the bear ate only fresh fish, it would need
{{{ 30*100 = 3000 }}} pounds for 100 days
---------------------
There are only 2000 pounds which is good for
{{{ 2000 / 30 = 66.667 }}} days
---------------------------
So the bear needs enough dried fish for 
{{{ 100 - 66.667 = 33.333 }}} days
{{{ 10*33.333 = 333.333 }}} pounds of dried fish
The bear needs 333.333 pounds of dried fish
during the 100 day visit
