Here is my problem. I bought my son Tommy, his back to school clothes. I can’t tell you how happy he is too being going back.

Tommy now has,
7 Shirts:
7 Pants:
3 pairs of shoes:

How many different possible outfits can Tommy make?

Answer would be,
7x7x3=147

147 possible outfits can be made.
Is this correct?

yes

Yes, your answer is correct. To find the number of possible outfits Tommy can make, you need to multiply the number of choices he has for each item of clothing.

In this case, Tommy has 7 choices for shirts, 7 choices for pants, and 3 choices for shoes. To calculate the total number of outfit combinations, you multiply these numbers together like this:

7 (shirts) x 7 (pants) x 3 (shoes) = 147

So Tommy can make 147 different possible outfits using the given number of shirts, pants, and shoes.
