Question 878602: Lisa works as a tutor for $7 an hour and a waitress for $14 an hour. This month, she worked a combined total of 106 hours at her two jobs. let t be the number of hours Lisa worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month. Answer by Jstrasner(112) (Show Source):
You can put this solution on YOUR website! 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!
