I need to buy enough white boards for 172 students and there are 25 in a pack when the pack arrives 12 whiteboards are damaged. How many whiteboards are undamaged?

So first we know that 12 are damaged and there are 172 students. So first we need to find out how many whiteboards did you buy without knowing there will be 12 damaged. The answer is 7 because there are 25 per pack. And 7 * 25 = 175. You can't buy less because you rather buy extra rather then not enough. Now knowing that, what is 175 - 12 because 12 was damaged.

175 - 12 = 163.

There are 163 whiteboards undamaged.
