Heidi has a brown pair and a gray pair of slacks; a brown blouse, a yellow blouse, and a white blouse; and a blue sweater and a white sweater. How many different outfits does she have if each outfit she wears consists of slacks, a blouse, and a sweater?

is the answer 12 outfits

Yep, it's 12 different outfits.

To determine the number of different outfits Heidi can have, we need to multiply the number of options for each clothing item together.

First, we have two options for slacks: brown or gray.
Second, we have three options for blouses: brown, yellow, or white.
Third, we have two options for sweaters: blue or white.

To find the total number of outfits, we multiply the number of options for each item together: 2 options for slacks * 3 options for blouses * 2 options for sweaters = 12 different outfits.

So, the answer is indeed 12 outfits.
