*Just a FYI, I am going to assume that you want to put the word coat between "and" and "110", and also "costs" and "100".
If a hat and a coat combined is 110 dollars, it is like this-
H=hat
C=coat
H+C= $110
If the coat costs 100 more than the hat, it is like this-
110-*100= h
* We replaced the c with 100
So we know that the coat costs 100, and since it is up to 110, it is automatically assumed that the coat is 100.
110-100 is 10, so the coat costs 100 dollars, while the hat costs 10.
Coat is 100, Hat is 10
