<u><em>Answer:</em></u>
Rosie now has c+3 charms
<u><em>Explanation:</em></u>
We are given that the original number of charms that Rosie has is c
We know that Ray gave Rosie 3 new charms
This means that the number of charms that Rosie originally had increased by 3
To express this increase, we use <u>addition</u> where we add 3 to the original number of charms that she had
New number of charms = original number of charms + 3
New number of charms = c + 3
