From the question

Melissa earns $12 an hour as a tutor

And $11 an hour as a waitress

Also,

This month, she worked a combined total of 105 hours

at her two jobs.

Let t be the number of hours Melissa worked as a tutor this month

Let w be the number of hours Melissa worked as a waitress this month

This implies

[tex]t+w=105[/tex]

Since Melissa worked t hours as a tutor this month then

Total money earned as a tutor = $12t

Also,

Since Melissa worked w hours as a waitress this month then

Total money earned as a waitress this month = $11w

Therefore, the total combined earnings for the month is

[tex]\text{ \$12t }+\text{ \$11w}[/tex]
