Question 274619: 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 subfloor. They can do this in one of two ways.
They can put 1/2 -in. sheet on top of 5/8 -in. board (note that the total would be 9/8 ft or 1 1/8 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.

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 1/2-in. sheet and a 5/8 -in. sheet?
2. What is the combined price for a 3/8-in. sheet and a 3/4-in. sheet?
3. What other combination of sheets of plywood yields the needed 1 1/8 -in. thickness?
4. Of the four combinations, which is most economical?

in question 4.
