Answer:

19.99

Explanation:

The steps are what I did, so no need to do it the exact same!

1. Add 4.50 and 3.4

4.50 + 3.4 = 7.9

2. Add 7.9 and 12.09

7.9 + 12.09 = 19.99

Hope this helps!

Answer:

The answer to this equation is 19.99. If you round the number, it is 20.

Explanation:

     4.50

     3.40 (0 as a place holder)

+   12.09

-------------------

     19.99 because . . .

4.5 + 3.4 = 7.9

7.9 + 12.09 = 19.99.

19.99 ≅ 20.00 or 20<em> (IF YOU NEED TO ROUND IT, IF NOT,</em><em> IT IS JUST 19.99!!!</em><em>)</em>
