Looks like there is a typo in the question. We will assume that the question is:

"A local department store sold carpet in 4 sizes.Each carpet came in 2 qualities. One size of carpet came in 7 colors. The other sizes came in 2 colors.How many choices of carpet were there?"

1*2*7 + 3*2*2 = 14 + 12 = 26

There were 26 choices of carpet.
