Question

I cut a long piece of wood into 50cm pieces. I manage to cut

w pieces of wood, and there is 20cm left over.

How long was the wood to start with?

Answer 1

`WoodLength = 50w + 20`

Explanation:

Given

Length of Pieces = 50cm

Number of Pieces = w

Left over = 20cm

Required

Determine the length of the wood

Start by multiplying the number of pieces by the length of each pieces

`Result = Length * Number`

`Result = 50 * w`

`Result = 50 w`

Lastly, add the leftover to get the actual length of the wood

`Wood Length = Result + Leftover`

Substitute 50w for Result and 20 for Leftover

`WoodLength = 50w + 20`

Hence, the length of the wood is 50w + 20
