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 1/8ft of sub floor. They can do this in one of two ways. They can put 1/2in. sheet on top of 5/8in. board (note that the total would be 9/8ft or 1 1/8ft). They could also put 3/8in. board on top of 3/4in. sheet. The table below gives the price for each sheet of plywood from a Home Depot store on 1/15/04.

Thickness cost for a 4ft x 8ft sheet.

1/8in. $9.15
1/4in. $13.05
3/8in. $14.99
1/2in. $17.88
5/8in. $19.13
3/4in. $21.36
7/8in. $25.23
1 in. $28.49

1. What is the combined price for a 1/2in. sheet and a 5/8in. sheet?

2. What is the combined price for a 3/8in. sheet and a 3/4in. sheet?

3. What other combination of sheets of plywood yields the needed 1 1/8in. thickness?

4. Of the four combinations, which is most economical?

5. The kitchen is to be 12ft X 12ft. Find the total cost of the plywood you have suggested in question 4.
