Question

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.

Answer 1

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
