Answer:

There are 28 blue marbles.

Step-by-step explanation:

Antonio has 15 green marbles and 12 red marbles. The rest of the marbles are blue.

Let the number of blue marbles be x

Total marbles green plus red = $15+12=27$

Now, Antonio has a total of 55 marbles.

Equation forms:

$55=x+27$

We will subtract 27 from 55 to get x.

= $55-27=x$

Hence x = 28

Therefore, there are 28 blue marbles.
