Explanation:

Let’s walk through this step by step:

- People who went to Mall D on Friday: 320

- Mall E on Thursday gets 80% of that: 0.8 × 320 = 256

- Now, total people at Mall C over all three days:

- Friday: 280

- Saturday: 360

- Sunday: 260

- Total: 280 + 360 + 260 = 900

- We need the average of 256 (Mall E, Thursday) and 900 (Mall C, all days):

- (256 + 900) / 2 = 1156 / 2 = 578

Here’s the catch: you need to divide by 2, not by the number of days or malls.

Now, check the options:

- Option 1: 260

- Option 2: 295

- Option 3: 289

- Option 4: 284

- Option 5: 270

- The correct answer is none of these per this calculation, but maybe they meant average across all three Mall C days and Mall E Thursday, so:

Let’s try averaging *all four numbers* (Mall E Thursday + Mall C Friday + Mall C Saturday + Mall C Sunday):

- That’s (256 + 280 + 360 + 260) = 1156

- 1156 / 4 = 289

So, with this logic, Option 3: 289 is the right pick.

- Option 3 (289) is correct.

- You averaged 256 (Mall E, Thursday) and each Mall C day (280, 360, 260), dividing by 4 as in the options—so you followed the intended logic.

- The question could trip you up with the wording, but you got it.
