Respuesta :

41% of 400 is 164 22% of 400 is 88 164-88=76 hope this helps

Answer: D. 76

Step-by-step explanation:

Since, the total number of people = 400,

By the given diagram,

The percentage of the number of people who prefer to watch WWCN = 41 %

⇒ The number of people who prefer to watch WWCN = 41% of 400 = 0.41 × 400 = 164

Now, The percentage of the number of people who prefer to watch WANR = 22 %

⇒ The number of people who prefer to watch WANR = 22% of 400 = 0.22 × 400 = 88

Thus, the difference between the number of people who prefer WWCN and WANR = 164 - 88 = 76

⇒ Option D is correct.
