Question

If 3/8 + 3/4 = $36.35 and the room to cover is 12 ftX 12 ft how much will the total cost be.

I do not want the answer, I want you to explain to me HOW to GET the answer.

Answer 1

Are you sure this is the entire problem? It doesn't make any sense to me.

Answer 2

Benjamin and Olivia are putting a new floor in their kitchen. To get the floor up to the
desired height, they need to add 1 ft of subfloor. They can do this in one of two ways.
They can put -in. sheet on top of -in. board (note that the total would be ft or 1 ft).
They could also put -in. board on top of -in. sheet.
The table below gives the price for each sheet of plywood from a Home Depot store
