First, count how many representatives stayed at least two nights.
[tex]11 + 14 = 25[/tex]
Now, 11 of the 25 representatives rented a car.
Therefore, you should make a percentage proportion.
[tex] \frac{11}{25} = \frac{x}{100} [/tex]
Solve for the variable, and it should give you [tex]x = 44%[/tex]
The answer is B. 44%.
