Nikki is buying some refrigerator magnets for her friends. Her total bill is $27.20. If magnets are $0.80 each, how many magnets is she buying? (Please show work!)

From the information we have, we know that the total amount of money she will  pay for all the magnets amounts to 16.80 dollars.

We also know that the price or cost of a single magnet is 0.80 dollars each.

Now we simply divide  her total bill with the price of one magnet, so:

16.80/0.80 = 21

Therefore the total number of magnets she is buying is 21

We can make the calculation also by removing the decimal points This makes it a bit more easier for calculation. We multiply each by 100 to eliminate  the two decimal places:

16.80 * 100 = 1680

  0.80 * 100 = 80

Now we can easily divide these numbers  and we end up getting the same answer, so:

1680/80 = 21

So, Nikki buys 21 magnets.
