If there are n survivors, there are 5n meals.
After 2 days, 2n meals have been eaten, leaving 3n
Then the 3n meals lasted the n-4 survivors 5 days:
3n/(n-4) = 5
Now just find n
After 2 days, 2n meals have been eaten, leaving 3n
Then the 3n meals lasted the n-4 survivors 5 days:
3n/(n-4) = 5
Now just find n
lim-ml
n=10
