Question 628776: John works as a tutor for $12 an hour and as a waiter for $8 an hour. This month, he worked a combined total of 86 hours at his two jobs.
Let be the number of hours John worked as a tutor this month. Write an expression for the combined total dollar amount he earned this month.
I am really confused how to set this up..
i tried 12t+8(86-t)=86 but that's not right & i can't figure out how to set this problem up. Answer by graphmatics(170) (Show Source):
You can put this solution on YOUR website! Your solution is nearly correct. You need an additional variable for total dollar amount. So let y be total dollar amount, then the expression is y=12t+8(86-t).
