You pack sandwiches for a mountain hike with your friends. Each sandwich takes 2 slices of bread, and each hiker eats one sandwich.

How many slices of bread are used for n hikers?

Write your answer as an expression.

2 (n)

Step-by-step explanation:

You pack sandwiches for a mountain hike with your friends.

Each sandwich takes 2 slices of bread.

If each hiker eats one sandwich, and there are 'n' hikers

so to find the number of breads used for 'n' hikers, we multiplied 2 by n

So the expression will be

2 (n)

2 (n) equals pieces of bread you'll need
