Answer:

The answer is D.

Step-by-step explanation:

First, you have to find the differences in number of guests in this 2 party :

[tex]31 - 20 = 11 \: guests[/tex]

Next, you have to divide by the smaller value which is the first party, then, multiply by 100 as the question wants percentage increase :

[tex] \frac{11}{20} \times 100 = 55\%[/tex]
