Answer:
140 individuals were surveyed
42 people are planning on going to the mountains
Step-by-step explanation:
The question is missing the information regarding the percentage of people who said that they were going to each of the possible destinations. After a quick google search I've found that, in the original question, 32% of individuals were going to the beach, 15% to the desert, 23% to major cities, and 30% to the mountains.
If 21 people said they were going to the desert, and that corresponds to 15% of the total number of people surveyed, the number of people surveyed is:

140 individuals were surveyed
Since 30% responded "the mountains", the number of people planning on going to the mountains is:

42 people are planning on going to the mountains

Step-by-step explanation:
So @mathmate deleted my comment because "I wasn't explaining my answer" well I did
I clearly stated that you have to make educated guess and I showed how I GOT my answer
so i guess here is my "proper" answer
There is no specific formula for this, so you can make an educated guess
for example:
13*5 = 65 (this isn't right because we need a minimum of 114)
so we continue the guessing
I then next tried
13*9
I got 117,
117 is more than 113
making 9 the minimum amount of rows for the hotel parking lot
there ya go @mathmate is that clear enough?
For the last one is the pi sign and 2.333
