We have:

$\frac{11}{12} - \frac{1}{3}$

Take LCM and solve

$\frac{11}{12} - \frac{1}{3} = \frac{11 - 4}{12}$

$\frac{11}{12} - \frac{1}{3} = \frac{7}{12}$

$72,00?

I'm assuming you are saying $7200, but if you are saying $72, just replace.

So you would get $432. But trust me, no house is that cheap lol
