Answer:
The problem only includes blue marbles.
Step-by-step explanation:
Lets visualize this.
(the O represents marbles)
Alyssa has 2 marbles --> O O
Jason has 6 marbles --> O O O O O O
Let's count them. How many marbles do we have all together?
O O O O O O O O
1 2 3 4 5 6 7 8
So that's 8 marbles! You have 8 total marbles.
I hope this helps!
