1.A company designs jackets that have stripes of equal width but different color.The background color of the jackets is different than the color of any of the stripes. How many different color patterns can the company prdouce if it stocks material in 12 colors

Assuming all stripes are the same color, 12 x 11 = 132
You multiply by 11 because, for each of twelve stripe colors, the background has to be one of the other 11 colors.
