Rachel works as a tutor for $15 an hour and as a waitress for $8 an hour. this month, she worked a combined total of 109 hours at her two jobs. let t be the number of hours rachel worked as a tutor this month. write an expression for the combined total dollar amount she earned this month.

$ (7t+872)

Step-by-step explanation:

Earning for 1 hour as a tutor= $15

Earnings for 1 hour as a waitress= $8

Total hours worked in the month combined jobs= 109 hrs

Number of hours worked as tutor for the month= t

Find the number of hours worked as waitress for the month= 109-t  hours

Total amount earned that month = amount earned as a tutor+ amount earned as a waitress

Amount earned as a tutor=  $15 × t = $15t

Amount earned as a waitress= $8× (109-t)= $ (872-8t)

Total amount earned combined= $ 15t + $ (872-8t)

                                                    =$ ( 15t-8t +872)

                                                    = $ (7t+872)

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
