First, can you write the expression for the amount earned working for t hours at $7 an hour?

kropot72 · Answer

The amount earned as a tutor is the hourly rate ($7 an hour) times the number of hours (t).

kropot72 · Answer

The amount earned as a waiter is the hourly rate ($9 an hour) times the number of hours. In this case the number of hours as a waiter is (106 - t).

The combined total dollar amount earned is the sum of the amount earned as a tutor and the amount earned as a waiter. Now you need to put these together.
