Question

Bricks 200+ 150+ . 100 50 * Layers 1 2 3 4 5 How many bricks are used in 1 layer of the wall? bricks

Answer 1

As you can see in the graph, the relationship between the number of bricks used and the number of wall layers is linear, so you could use the rule of three to solve the exercise, like this

`\begin{gathered} 2\text{ layers}\rightarrow100\text{ bricks} \\ 1\text{ layer}\rightarrow x\text{ bricks} \end{gathered}`
`\begin{gathered} x=\frac{1\text{ layer}\ast100\text{ bricks}}{2\text{ layers}} \\ x=50\text{ bricks} \end{gathered}`

Therefore, 50 bricks are used in 1 layer of the wall.
