The store clerk has 21 mugs to display on shelves. she wants to display an equal number of mugs on each shelf with no mugs left over. which problem below shows a way she can do this?

The concept to do this question is to break the number into its factors and then make different combination.

The given number has just two factors

The factors of 21 are 3 & 7.

Which means

21 = 3 × 7.

So

Either we can have 7 shelves with 3 mugs on each shelf.

Or

We can have 3 shelves with 7 mugs on each shelf.

This way as 21 is divisible by 3 & 7. No mugs shall be left out.

So We have two solutions to this.

7 shelves with 3 mugs on each shelf.

3 shelves with 7 mugs on each shelf.

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
