Answer:
The correct answer is 64 marbles.
Step-by-step explanation:
Let's analyze the information we have:
Jill has 4 bags of marbles.
In each bag she has 16 marbles (in each one she has 3red, 5green, 2 yellow, and 6black)
If each bag has 16 marbles, and she has 4 bags, then we must multiply the contents of each bag by 4.
And we do it as follows:
16 x 4 = 64
Therefore, we can say that Jill has 64 marbles.
