Amanda has 3 skirts, and 3 pair of shoes. How many different outfits could she make?

Yeah and also because 3*3 = 9 thats just an easier way to do it but you can match and label pairs if your'e a visual learner

I'm going to assign each skirt a letter and each pair of shoes a number:

Skirt A, Skirt B, Skirt C

Pair 1, Pair 2, Pair 3

Now, I'll put them together into skirt/shoe pairs:

Skirt A and Pair 1

Skirt A and Pair 2

Skirt A and Pair 3

Skirt B and Pair 1

Skirt B and Pair 2

Skirt B and Pair 3

Skirt C and Pair 1

Skirt C and Pair 2

Skirt C and Pair 3

Altogether, there are 9 skirt/shoe pairs. So, Amanda could create 9 different outfits.
