Question

a knitted hat pattern comes in 4 styles with 3 stitch options and 3 sizes, and there are 7 yarns appropriate for the hat. disregarding style, how many different hats can be made? there are \boxed{} different hats that can be made.

Explanation:

Step1: Identify relevant options (disregard style)

We ignore the 4 styles. So we consider stitch options (3), sizes (3), and yarns (7).

Step2: Apply multiplication principle

To find the number of different hats, we multiply the number of options for each category: stitch options × sizes × yarns. So it's $3\times3\times7$.

Step3: Calculate the product

First, $3\times3 = 9$. Then, $9\times7 = 63$.

Answer:

63
