Answer:

H - 5 hours

Step-by-step explanation:

We can setup an equation to solve the question.

Let [tex]h[/tex] be the number of hours Mary must work.

[tex]250 = 160 + 3(6h)[/tex]

250 - the amount of money Mary needs

160 - the amount of money Mary has saved already

3 - How many days she works

6h - How much she gets paid per day

[tex]250 = 160 + 3(6h)\\90 = 3(6h)\\90=18h\\5=h[/tex]

This means Mary must work 5 hours each day to pay her rent.
