7 people are coming to Karla's house to watch a football game. She wants to make sure each person, including herself, will get \( 1 / 2 \) of a Subway sandwich. How many sandwiches will she need to buy?

To figure out how many sandwiches Karla needs, we first calculate the total number of people watching the game, which includes herself and the 7 guests. This totals 8 people. Since each person will eat \( \frac{1}{2} \) of a sandwich, we can calculate the total amount of sandwiches needed by multiplying the number of people by the amount of sandwich each will consume: \[ 8 \text{ people} \times \frac{1}{2} \text{ sandwich/person} = 4 \text{ sandwiches} \] So, Karla will need to buy 4 sandwiches to ensure that everyone gets their share!
