Answer :
To work out how much Luz earns, you simply have to follow 400/40=10, so
she earns $10/hour. We can therefore establish that if she works for 6
hours, she'll earn $60.
For this case we can make the following rule of three:
$ 400 -------------------> 40 hours
x ------------------------> 6 hours
From here, we clear the value of x.
We have then:
[tex] x = (\frac{6}{40}) * (400)
x = 60
[/tex]
Therefore, Luz earns $ 60 for 6 hours of work.
Answer:
she earns $ 60 for 6 hours of work
