Fourteen is 28% of B) 50
Why, you ask? Let's see -
Let the unknown number be n, for 'number'.
Let's put the unknown n next to 28%
.28n% = 14
(Think, what times .28 equals 14? Look below to find out! ↓ )
Let's now do the opposite of the actual equation - divide the two known numbers by each other -
.28 ÷ 14 = 50
When in doubt, check your answer:
To check this, we would do the opposite - Multiplication
Multiply .28 by 50 to get 14 (At least you should get 14)
.28 × 50 DOES EQUAL 14! We were right! :D

TLDR: 241 clients will be taking +3 vacations.
This is a common example of representative scale size, or sample size. In selecting a small amount of people at random from a larger group, one can estimate the amount of people in the large group picking a specific answer based on a smaller, but proportionate, group size.
In the sample size, 21 of the 45 tested people said that they would go on more than three vacations a year, and this scale is supposedly proportional to the total group. Therefore, we can use a simple proportion to estimate the amount of people who would also say that they are going on more than three trips a year:
21 would ‘N’ would
————— = ——————
45 total 516 total
where N represents the number of people in the big group that would go on more than three trips a year.
Solve the proportion by cross-multiplication:
45N = 10,836
N = 240.8 people, or 241 people.
Based on the sample data, 241 people out of the 516 total will be taking more than three vacations a year.
