Answer:

No, Zahra does not have enough staff available

Step-by-step explanation:

Given

[tex]Ratio = 2 : 15[/tex] --- staff to people

[tex]Staff = 10[/tex]

[tex]People = 90[/tex]

Required

Are there enough staff?

Start by representing the data as a ratio

[tex]Ratio = Staff : People[/tex]

So, we have:

[tex]Ratio = 10 : 90[/tex]

Divide by 10

[tex]Ratio = 1 : 9[/tex]

Multiply by 2

[tex]Ratio = 2 : 18[/tex]

This means that, she has 2 members of staff for every 18 people (instead of the expected 2 to 15 people)

Hence, Zahra does not have enough staff available
