You pack sandwiches for a mountain hike with your friends. each sandwich takes 2 slices of bread, and you pack 3 sandwiches for each hiker. how many slices of bread are used for n hikers? write your answer as an expression.

Let n = number of hikers

y = number of slices of bread per sandwich = 2

x = number of sandwiches for each hiker = 3

T = total number of slices of bread used for "n" hikers

The expression below represents the total number of slices of bread used for "n" hikers:

T = 2 slices * 3x sandwiches * n hikers
