Ravi works as a tutor for
$
11

an hour and as a waiter for
$
7

an hour. This month, he worked a combined total of
98

hours at his two jobs.

Let
t

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

Answer 1

Kim, let's think about it.

 

Working as a tutor, he made 11t, right?

 

So, how many hours did he wait tables? 98 - t.

 

11t + 7(98 - t)

11t + 686 - 7t

4t + 686
