Answer:

She makes $ 144 for 9 hours of work.

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:


\bf{x=(288*9)/(18)=(2592)/(18)=144 }

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