Question

Jane is building eight 3-legged stools. Each leg is 1/2 yard long. She can cut the legs from wooden rods that are sold in 2-yard lengths. How many rods will she need to buy?

Answer 1

`n = 6\,rods`

Explanation:

The total of legs needed to build the stools are:

`x = (8) \cdot (3)`

`x = 24`

Likewise the total length of the legs is:

`L_(tot) = 24\cdot (0.5\,yd)`

`L_(tot) = 12\,yd`

Lastly, the quantity of rods that needed to buy is:

`n = (12\,yd)/(2\,(yd)/(rod) )`

`n = 6\,rods`
