bob wants to pass through the canyon but the sphinx is blocking the way. 'You must answer my riddle', says the Sphinx, 'if 500+250x=300x, find x. I need it because my baker wants to know the answer because his uncle's son's grandma's father wants to solve his problems with this magic equation'
If bob answers correctly, then he will live. If not he will die.
(certainly this is a real life application for those traveling through canyons)
(ok, joking aside the answer is
there are some people in a bank
500 water bottles are lost
if each person was given 250 bottles, then they would have given away all of the bottles.
if they had not lost the bottles, then they would have been able to give 300 bottles, how many people were there?)
