To find the minimum number of cars that would be in accidents,
we need to assume maximum cars are involved in exactly four accidents.

Since there are a total of 36*10000 accidents that take place in 1993,
the number of accidents taking place in 1993 is $$\frac{36*10000}{4} = 90$$ thousand(Option E)

This prompt's lesson: look carefully at the legends.

The uselessness of the second graph should be apparent immediately from its legend "in millions."

Accidents are reported in "teen thousands." Division is necessary, and there are no fractional accidents.

1993 had 360,000 accidents. At four per car, minimum number of cars involved is 90,000.
