Maria works as a tutor for $10 an hour and as a waitress for $14 an hour. this month, she worked a combined total of 83 hours at her two jobs. let t be the number of hours maria worked as a tutor this month. write an expression for the combined total dollar amount she earned this month.

$ (-4t+872)

Explanation:

Earning for 1 hour as a tutor= $10

Earnings for 1 hour as a waitress= $14

Total hours worked in the month combined jobs= 83 hrs

Number of hours worked as a tutor for the month= t

Finding the number of hours worked as a waitress for the month= 83-t  hours

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

Amount earned as a tutor= $10 × t = $10t

Amount earned as a waitress= $14× (83-t)= $ (1162-14t)

Total amount earned combined= $ 10t + $ (1162-14t)

                                                   =$ ( 10t-14t +1162)

                                                   = $ (-4t+872)
