Answer:

Megan added 4 rocks.

Step-by-step explanation:

We know this because if the box had 8 rocks in it intially and it now has 12 rocks, we know that Megan added 4 rocks. Since, 8+4= 12 or 12-8=4

Equation form:

r = how many rocks Megan added

8+r=12

12-8=4

r=4

Megan added 4 rocks.

Hopefully this helps!! ^^
