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?
