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

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

who said they each ate 3x sandwiches?

2 slices/sandwich * 1sandwich/hiker * n hikers = 2n slices of bread

nx2 is the answer

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
Hint #22 / 3
Hikers Slices of bread
\blue{n}nstart color #6495ed, n, end color #6495ed 2 \cdot \blue{n} = 2n2⋅n=2n2, dot, start color #6495ed, n, end color #6495ed, equals, 2, n
Hint #33 / 3
The answer: 2n

To find the number of slices of bread used for nhikers, you can multiply the number of hikers by 2 (since each hiker eats one sandwich and each sandwich takes 2 slices of bread). So the expression would be:

Number of slices of bread = nhikers * 2

This expression will give you the total number of slices of bread used for nhikers.

hold on dude, just one second

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
