Answer:

She makes $ 144 for 9 hours of work.

Step-by-step explanation:

A simple rule of three:

If  288 for 18 then

   X  for 9

X = (9*288)/18

X =  2592/18

X = 144

We apply the rule of three:

Payment---------------------time

  $288--------------------------18

      x-----------------------------9

First multiply 288 by 9, and then divide by 18, so:

[tex]\bf{x=\dfrac{288*9}{18}=\dfrac{2592}{18}=144 }[/tex]

Therefore, Debora would earn $144 for 9 hours of work.
