need help with this;

There are 50 floors on a building. 25 are painted red and 25 and painted blue. The number of red floors on the top half plus the number of blue floors on the bottom half are equal to 28. How many red floors are there on the top half?

To solve this problem, we need to break it down and analyze the information given step by step.

Let's start by considering the total number of floors on the building, which is 50.

Since we are asked to find the number of red floors on the top half, we can assume that the first floor is at the bottom and the 50th floor is at the top.

Next, we are given the information that there are 25 red floors and 25 blue floors.

We are also told that the number of red floors on the top half plus the number of blue floors on the bottom half equal 28.

To approach this problem, we can divide the total number of floors in half to determine the split between the top and bottom halves.

Since there are 50 floors in total, half of 50 is 25. Therefore, the first 25 floors make up the bottom half, and the last 25 floors make up the top half.

Now, let's analyze the given information that the number of red floors on the top half plus the number of blue floors on the bottom half equals 28.

Since there are 25 red floors in total, we can see that the number of red floors on the top half must be less than or equal to 25.

Similarly, since there are 25 blue floors in total, the number of blue floors on the bottom half must also be less than or equal to 25.

Considering this, we can see that it is not possible for the sum of red floors on the top half and blue floors on the bottom half to be 28, as this would require both numbers to be greater than 25.

Therefore, based on the given information, it is not possible to determine the number of red floors on the top half.
