Answer 9

Keith works as a tutor for
$8
an hour and as a waiter for
$12
an hour. This month, he worked a combined total of
106
hours at his two jobs.

Let
t
be the number of hours Keith worked as a tutor this month. Write an expression for the combined total dollar amount he earned this month.

Answer 10

t = number of hours worked as a tutor
106 - t = number of hours worked as a waiter

8t + 12(106-t) is how much he will earn in total this month

So just simplify it. First distribute the 12, and then add/subtract like terms.

And that's your final answer :)

Answer 11

8t+1272-12t
-4t+1272=0
+4t +4t
318.25 is that right?

It wants total earned in dollars
