Question 878602
Hello,

So for this one we need to write an expression that represents the hours Lisa worked as a waitress.

First we write how she how much she made as a tutor:

t (hours) x $7/hour 

To write the hours she didn't work as a tutor we simply subtract t from 106:

(106-t) 

So the combined expression is:

(t x $7/hour) + ((106-t) x $14/hour)) 

I hope this helps!
