Where's your attempt at this problem?

First choice AND THEN second choice AND THEN third choice

I'll let you do this;

Hint: AND THEN means multiplication.

After you have attempted the problem,

Answer: *6*

Okay.

Let's see:

4 times 3 times color (which) I'll call x.

We have:

4 times 3 times x = 72

12x = 72

x = 6 = Kimberly's choices of color, right?
