Eleanor is building shelves to hang in her club she uses 36.5 feet of wood. Each shelf is w feet long. Create an expression that will represent the number of shelves Eleanor builds from the wood.

Let n represent the number of shelves Eleanor builds. Since each shelf is w feet long, the total length of wood used for n shelves is n * w feet.

Given that Eleanor uses 36.5 feet of wood, we can set up the equation:

n * w = 36.5

Therefore, the expression that represents the number of shelves Eleanor builds from the wood is:

n = 36.5 / w
