Step-by-step explanation:
We desire to evaluate the fraction: 
when k=3.
This is a simple substitution, so what is required is
- Replace k with the given number
- Simplify the resulting expression
Therefore, when k=3
You can try the same for any value of k.

Answer:
45 people prefered coffee, 81 people prefered tea. A total of 126 people were surveyed.
Step-by-step explanation:
Let t be the people who prefer tea, and let c be the people who prefer coffee.
The ratio between tea and coffee is 9:5, thus we have t/c=9/5. Cross products give us 5t=9c.
Also, we have 36 more people prefer tea than coffee, so we have c+36=t
Thus we have: 5(c+36)=9c
5c+180=9c
180=4c
c=45
c+36=t
45+36=81
