For the graffiti cat sweater, Dodd knit 12 stitches to make 2 inches in width. The sweater is 9 inches wide from the left edge to the beginning of the black smile. How many stitches wide is that?

54 stitches

Step-by-step explanation:

12 stitches = 2 inches

Solving for PER INCH,

12/2 = 6

So,

There are 6 stitches PER INCH

Now, we need to find the number of stitches in 9 inches. That would be:

6 stitch / 1 inch means:

6 * 9 = 54 stitches

There are 54 stitches in 9 inches
