Explanation:

Nice work on selecting the correct equation to set up.

We'll cross multiply to help solve for x.

The idea of cross multiplication is that $\frac{A}{B} = \frac{C}{D}$ turns into $A*D = B*C$

So,

$\frac{5040}{280000} = \frac{x}{800000}\\\\5040*800000 = 280,000*x\\\\4,032,000,000 = 280,000x\\\\280000x = 4,032,000,000\\\\x = \frac{4,032,000,000}{280,000}\\\\x = 14,400$

That means the person would pay $14,400 on a property worth $800,000.
