Mathematics.

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 3/8-in. board on top of 3/4-in. sheet. The table below gives the price for each sheet of plywood from a Home Depot store on 1/15/04.

247 2005 Thickness Cost for a 4 ft  8 ft Sheet
1/8 in. $9.15
1/4 in. 13.05
3/8 in. 14.99
1/2 in. 17.88
5/8 in. 19.13
3/4 in. 21.36
7/8 in. 25.23
1 in. 28.49

3. What other combination of sheets of plywood yields the needed 11/8 -in. thickness?
