Answer:
$ (-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)
