Jenny works as a tutor for 14 an hour and as a waitress for 8 an hour. This month, she worked a combined total of 100 hours at her two jobs.
Let t be the number of hours Jenny worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month.

Let $ t $ represent the number of hours Jenny worked as a tutor this month. Since she worked a combined total of 100 hours at both jobs, the number of hours she worked as a waitress can be represented by $ 100 - t $.

Jenny earns $14 per hour as a tutor and $8 per hour as a waitress. Therefore, her total earnings from each job can be written as:

- Earnings from tutoring: $ 14t $
- Earnings from waitressing: $ 8(100 - t) $

To express the combined total amount she earned this month, add these two expressions:

\[
\text{Total earnings} = 14t + 8(100 - t)
\]

This expression represents the total dollar amount Jenny earned this month.
