Question

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. (square) slices of bread

Explanation:

Step1: Determine sandwiches for n hikers

Each hiker eats 1 sandwich, so for \( n \) hikers, number of sandwiches is \( n \times 1 = n \).

Step2: Calculate bread slices for n sandwiches

Each sandwich needs 2 slices of bread. So for \( n \) sandwiches, bread slices are \( n \times 2 = 2n \).

Answer:

\( 2n \)
