Answer:

#$840#

Explanation:

Let's first set up an equation and identify the variables.

We are given that #$7# is earned every hour worked. We can represent this mathematically as: #7x#, where #x# represents the number of hours. If we were to say this aloud, we would be saying "seven dollars per hour".

#7x#

To make this an equation that can be solvable, we need to set this term equal to something, and we can use another variable.

#y=7x#

We are told that #120# hours were worked. We can plug this into #x#, since #x# represents hours.

#y=7(120)#

Now we need to simplify. Multiply #7# and #120#.

#y= 840#

We found out that #$840# was earned when #$7# was made every hour, for #120# hours.
