A desk costs $44, but they boost the price 150%
[tex]44( \frac{150}{100} ) = 66
[/tex]
They are selling it at $66 (selling price)
Since Michelle sold it at $66 and she earns 20% on the selling price as commission, then it is simply
[tex]66( \frac{20}{100} ) = ?[/tex]
That should be the commision amount michelle earns
