Your answer is going to be “C”.
Answer:

Step-by-step explanation:

Since the company wants to survey 500 customers by the countries visited, the number of samples from each country will be proportional to the number of customers.
For UK, Number of Samples
For France, Number of Samples
For Spain, Number of Samples
For Italy, Number of Samples
The completed table therefore is:

The value of x is 8
- This question is a proportion. To solve it, let's assemble it as follows:
<u>5</u> = <u>4</u>
10 x
- Now, just multiply in the form of a cross. Then, let's split the terms:
5 . x = 10 . 4
5x = 40
x = 40 ÷ 5
<u>x = 8</u>
So, the result of x will be 8
The way to answer this problem given different points and different equations in the choices is to do substitution and trial and error. In this regard, we substitute for example 4 to x in the equations and check which of them yields 89. The answer is D.
