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

Question

How many slices of bread are used for nhikers?
Write your answer as an expression.

Answer 1

hold on dude, just one second

Answer 2

here
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

Answer 3

who said they each ate 3x sandwiches?
2 slices/sandwich * 1sandwich/hiker * n hikers = 2n slices of bread

Answer 6

Let's see what happens as the number of hikers increases:
Hikers Slices of bread
\blue{1}1start color #6495ed, 1, end color #6495ed 2 \cdot \blue{1} = 22⋅1=22, dot, start color #6495ed, 1, end color #6495ed, equals, 2
\blue{2}2start color #6495ed, 2, end color #6495ed 2 \cdot \blue{2} = 42⋅2=42, dot, start color #6495ed, 2, end color #6495ed, equals, 4
\blue{3}3start color #6495ed, 3, end color #6495ed 2 \cdot \blue{3} = 62⋅3=62, dot, start color #6495ed, 3, end color #6495ed, equals, 6
