How much Rita earns?

Judging by the first posted image, which is nearly impossible to read, you have left out some information here.

I recommend typing out the entire question, along your work so we can easily read it. Most people are not going to attempt to help if it is a struggle to do so. I'm not trying to be harsh, just honest. :D

Okay, we could label the amount Rita earned as $R$ and the amount Vickey earned as $V$ (both amounts in dollars). Now, can you express the following as an equation?

Vickey earns \$900 less than Rita.

Rather than simply posting the end result, it would be better for you to show your work. That way we can check your work rather than having to work the problem ourselves to check your answer. :D

To answer my previous post, we could write:

\(\displaystyle V=R-900\)

Now, we are also told that Rita spends 5/9 of her salary while Vickey spends 5/6 of hers and that the amount spent by Rita is twice that spent by Vickey, and so we may write:

\(\displaystyle \frac{5}{9}R=2\cdot\frac{5}{6}V\)

\(\displaystyle R=3V=3(R-900)=3R-2700\)

\(\displaystyle 2R=2700\)

\(\displaystyle R=1350\,\checkmark\)
