hi guy

i have a little math probleem i am having trouble with hope you could help.
a mountian clim
he needs to clim 3000m.
he can only carry 100 food.
1food = 10 m
there is an unlimited amount of food at base camp
he cant go all the way in 1 go so he needs to put up temporary camp where he stores food for later.
by store of foof he need to get to the top
you dont need to get his down from the top
