The camel gets 787 bananas to the other side.
he eats 4213 bananas.

thank u very much.

assumption -- he eats whole bananas and walks whole mile increments. u can probably squeeze a few more bananas out if u allow fractional miles. It is only 7 bananas going from 10 miles to 1 mile

explanation--- taken to the limit of 1 mile per load the first mile he eats 9 bananas, the second mile he eats another 9
...........
at the 888 mile marker he has 3993 bananas left and eat 8 in the last mile. etc. etc.

set it up in Excel

a1=1000,
a2=5000,
a3=mile increment

b1=IF(A1=0,"",IF(A1=
"","",A1-$A$3))

b2=IF(MOD(A2,1000)=0,
(A2-(A2/1000-1)*(2*$A$3)
-$A$3),IF(MOD(A2,1000)
<=$A$3,A2-ROUNDDOWN
(A2/1000,0)*(2*$A$3),A2-
ROUNDDOWN(A2/1000,0)
*(2*$A$3)-$A$3))

copy b1 and b2 right for 999 columns

set a3 to whatever u like - the limit is = 1

it will show wild turkeys answer correct but not optimum.

The camel is loaded up with 1000 bananas. He travels 333 1/3 miles into the desert, eating 333 1/3 bananas on the way, and unloads 333 1/3 bananas. This leaves him loaded with 333 1/3 bananas, which is enough to return him to his starting place. When he gets back, he is loaded up again with 1000 more bananas, and he repeats the same round trip. After four such round trips, he has left 4 x 333 1/3 = 1333 1/3 bananas at a place 333 1/3 miles across the desert, and he is at his starting place getting loaded with the last 1000 bananas. He travels again 333 1/3 miles to his banana stash, eating 333 1/3 bananas on the way, and arrives still loaded with 666 2/3 bananas, so now he is 333 1/3 miles across the desert with 1333 1/3 + 666 2/3 = 2000 uneaten bananas.
He doesn't need to go back to his starting place again because there are no bananas left there, so he loads up with 1000 bananas and travels 333 1/3 miles further into the desert, eating 333 1/3 bananas on the way, and unloads 333 1/3 bananas, then eats the remaining 333 1/3 bananas he is loaded with during his return to his first stash. He loads up with all 1000 bananas that he left there, and he heads back to his second stash. He eats 333 1/3 bananas on the way and when he gets there he is still loaded with 666 2/3 bananas. He left 333 1/3 bananas on his first trip there, so now he is 333 1/3 + 333 1/3 = 666 2/3 miles across the desert with 666 2/3 + 333 1/3 = 1000 uneaten bananas. He is loaded with all of them and travels the remaining 333 1/3 miles across the desert. He eats 333 1/3 bananas on the way, and he arrives at the other side of the desert with 666 2/3 uneaten bananas.

1000 bananas. because the camel has to walk through a 1000 mile desert and can only carry 1000 bananas at a time, so it ate one after each mile he walks.

Once the camel takes the 1st trip to the other side of the desert, he won't be able to return to the original point, so there will be 4000 bananas left at the original starting point.

786. You have to leave 18 bananas behind and walk 4206 miles. This solution deals only with whole numbers.
Walk 111 miles with 1000 bananas. Leave 778 bananas, go back for 1000 more. Repeat until you have 4001 bananas at mile 111 (9 trips of 111 mi.)
Carry 1000 bananas to mile 253 leaving 714 bananas and walk back to mile 111 for more. Repeat until you have 3002 bananas. (7 trips of 142 mi)
Carry 1000 bananas to mile 453. Leave 600 bananas and go back for more. Repeat until you have 2000 bananas. (5 trips of 200 miles)
Carry 1000 bananas 333 miles to mile 786. Leave 334 bananas and go back for more. Pick up the remaining 1000 bananas and go to mile 786. Pick up 333 bananas to fill up your 1000 (Feed the camel the last banana while he rests - he deserves it!) and walk to mile 1000. You arrive with 786 bananas.

The camel is driven to an airport and airlifted across the desert it doesnt even walk a mile and doesnt even eat one banana.

0, because if he can only carry 1000 bananas at a time and he has to eat one for every mile he walks, then 0
