A roller coaster can carry 36 people per run. how many times does the roller coast have to run to allow at least 10,000 people to ride?

36 ppl per run, 36x for x=Number of runs.

Set 10000=36x to solve for x.

x=10000/36 which is about 278 times.

The Problem changes if the amount of ppl getting on isn't constant, it's ultimately a question of the number of ways to partition 10,000 with values under 36.

For instance - 1 person at a time requires 10,000 rides.
