Solution:

The value of 350 marks in dollars is 350/0.497, which is approximately 350/0.5 = 700. Since 0.497 is slightly less than 0.5, 350/0.497 should be slightly greater than 350/0.5 = 700. Therefore, the correct answer is \$704.

Consider this:
$$0.497$$ marks $$= \1$$;

$$0.5$$ marks $$=$$ more than $$\1$$;

$$0.5\cdot 700=350$$ marks $$=$$ more than $$\1\cdot 700= \700$$.

Therefore, the correct answer is E

Since we are comparing marks with dollars, can solve the question using equivalent ratios

We'll use the ratio marks/dollars

Let x = the number of dollars equivalent to 350 marks

We can write: 0.497/1 = 350/x
Cross multiply to get: 0.497x = 350
Solve:x = 350/0.497

Important: Do NOT use long division to evaluate 350/0.497 (the test-makers do not care about your ability to be a human calculator)

Notice that 350/0.5 = 700
Since 0.497 is a little bit less than 0.5, we can conclude that 350/0.497 is a little bit bigger than 700
