First of all, check you answer for number 1 and make sure it's correct.
3. You need two sheets that equal 1 1/8 in. or 9/8 inches. So,
1 in. and 1/8 in. = 1 1/8
7/8 in. and 1/4 (or 2/8) = 9/8
3/4 (or 6/8) and 3/8 = 9/8
1/2 (or 4/8) and 5/8 = 9/8
Okay, I gave you that part. Now, for number 4. Figure out the cost for each of these, the cheapest will be the most economical. Then for 5, take this least amount and multiply it by the area of the floor (24 x 24)
Hope this helps! Good luck!
I really need help with this problem. I have NO IDEA how to get the answers to 3 and 5.
Benjamin and Olivia are putting in a new floor in thier kitchen. To get the floor up to the desired height, they need to add 1 1/8 ft. 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 98 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.
Thickness price
1/8 in. $9.15
1/4 in. $13.05
3/8 in. $14.99
1/2 in. $17.99
5/8 in. $19.13
3/4 in. $21.36
7/8 in. $25.23
1 in. $28.49
1. What is the combined price for a 1/2 in. sheet and a 5/8 in. sheet?
I got $37.01
2. What is the combined price for a 3/8 in sheet and a 3/4 in. sheet?
I got $36.35
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?
5.The kitchen is to be 12 ft �12 ft. Find the total cost of the plywood you have suggested
in question 4.
I have no idea how to come up with the last three answers. I don't want the answers, I just want to know HOW to work these problems. Any help would be greatly appreciated. Thanks!
