#7) Normal levels of the uranium-235 isotope are about 0.72%, with the majority being uranium-238. Round the level up to 1% (in the favor of uranium-238), to one atom of uranium-235 and 99 atoms of uranium 238. Use the
simulation to discover if naturally-derived uranium can start a chain reaction (and therefore be useful in either
nuclear weapons or nuclear power plants): Is naturally derived uranium able to start a chain reaction, or must the
sample be "enriched”?

C: 4 stops . You can tell this by reading the graph, find where 13 is on the y-axis (the left side going up) to find number of passengers and then go across to find how many stops for 13 passengers. In this case you have to read whats not on the graph and realize that 13 passengers is between the 12 and 16 points, a quarter of the way up
