Mrs. McKegney wants to tile her kitchen floor. The tiles are 3 inches on each side. The floor is 10' x 15'. How many tiles does she need?
The tiles are sold in bundles of 10. Each bundle costs $3.50. How many bundles are needed? How much will she need to pay for the tiles?
Write a letter to Mrs. McKegney clearly explaining your solution to her tile problem and how you went about solving the problem. Be sure to include a visual representation of your solution and observations that you made.

first I turned 10' in to 120''and turnd 15' in to 360'' then I multiplyed each one of those #'s and got 43,200 then found out that each tile covered 90sq inches and divided 43,200 by 90 and got 480 and that is th answer to the number of bundles I will neednow that I have the number of bundles I need I can multiply that by 10 and get the answer to the # of tiles qustion. and the Answer is 4800 tiles.
To get the # of $bills spent on the bundles I will multiply $3.50 by 480 bundles.Once I have the answer to that. I will have both of the answers to the equasion which is 1,680.00 dollers
# of tiles:4800
total doller bills spent:1,680.00
1. 10 x 15=150 % 3=50
2. 1. 50 % 10=5
3. $3.50 x 5=$17.5
4. for my first problem, I multiplied 10 by 15 and I got 150, then I divided it by 3 and got 50.Thats how I got my 1st answer.I got my 2nd answer by dividing 50 and 10 and got 5.I got my 3rd answer by multiplying $3.50 and 5 and got $17.5
First I converted 10 feet in to inches,then I multiplied 10 by 12 and 15 by 12. Finally I added 120 and 180, to get 300.
1. 10 ft = 12 in. each foot = 120 in.
2. 10 ft x 12 in. = 120 in.
3. 15 ft x 12 in. =180
4. 180 + 120 = 300
Dear Ms. Mcergney you will need 15 packs of tiles since 10x15=150 you will need to pay 35$ since 3.50x10=35.00.
Mrs, McKegney,
You will need 2,400 tiles, which you purchas in 240 bundles, and it will cost $840. To find this, first I multiplied the length times width of the room. Then I multiplied that by 16 tiles per foot to get 2,400 tiles. Second I divided 2,400 tiles by 10 and got 240 bundles. Last I multiplied 240 bundles by $3.50 per bundle and got $840.

first i need too do 10 x 15 then take that answer and do?x3 and thers the answer
second i need to divid 10 by the answer you got in the first problem and then you got the answer
first answer is 450 tiles needed
second answer is 45 packs needed
The first thing I did was look for key words like tiles and inches, which told me I was dealing with area. Then I multiplied 10' x 15' to get the area of the floor, which was 150 square feet, or in inches: 1,800 square inches. After that, since the tiles are 3 by 3 then I divided 1,800 by three to get 600 tiles. Then, since the tiles are sold in bundles of ten I divide 600 tiles by 10 tiles per bundle which gave me 60 bundles. Finally, to get how much it all costed, I multiplied 60 bundles by $3.50 and found out that everything costed $210.
That meant that there were 60 bundles and altogether everything costed $210.
The answer I got was 150 tiles then I got 15 bundles and then I got 38.00 dollars. I got the 150 from the 10x15 for the tiles.Then I got 15 bundles by sub ten 15 times. Then i got 38 dolllars fron adding three fifty 15 times.
Dear Mrs. Mckegney,
The area of the kitchen floor is 150 square inches. I know this because 10x 15 equals that since to multiply 10s you add a zero to whatever number your multiplying. Next, I divide 150 inches divided by 3 inches each square and that equals 50 tiles. Now you need to know the cost. First, you multiply $3.50 times 5 bundles which equals $17.50. You have to pay that much. :D
Sincerely, Eileen
the room is 10x15 and the tiles are 3" each. she will need 5 tiles on one side and 4 tiles on the other side. so she will need to buy 1 bundle for $3.50. she will have 1 tile leftover.
Mrs.Mckegney needs 2,400 tiles
she will need to buy 240 bundels
and it will cost $840.00
Dear Mrs.McKegney,
first,I found the area of your kitchen floor, which is 10x15=150
so, you need 150 sq feet. But your tiles are 3 inches in each side, so each one sq ft tile is 16 three sq inches tile, so I multiplied
150X16=2400.
So, you need 2400 3" sqare tiles.
the tiles are sold in bundels of ten. I divided 2400 by 10 which is 240, so you need 240 bundles of tiles. Each bundeles costs $3.50. I multiplied 240 with 3.50 and I got $840.00
Dear Mrs.McKegney,
To solve your tile problem, I took the length and width of your kitchen floor and multiplied them both by 12ft.The first answer would be 120ft for 10ft x 12ft and your second would be 180ft for 15ft x 12ft.I took those answers and divided them by 3in for the size of the tiles.Your answer for 120ft divided by 3in would be 40 tiles and for 180ft divided by 3in would be 60 tiles.I then took 60 tiles and 40 tiles and multiplied them.That answer would be 2,400 tiles.I am also aware of your problem with the amount you need to pay for the bundles.If each bundle holds 10 tiles and each bundle costs $3.50, you would divide 2,400 tiles by 10 tiles per bundle.Your answer would be 240 bundles.Now that you know you need to pay for 240 bundles, you can multiply that by $3.50.Your answer would be $840.00.So you need 2,400 tiles total,you need to buy 240 bundles, and your total cost is $840.00.-Emma Peters
Dear Mrs. McKegney,
I have done my calculations and your kitchen floor will cost you $840. You will need to buy 240 bundles of tile which cost $3.50 each.
You have 150 square feet of floor. Since each square foot will have 16 tiles, you will need a total of 2,400 tiles. (Each tile is 3 inches on each side.) I multiplied the total number of square feet by 16 to come up with the total number of tiles needed. The tiles come in bundles of 10, so I divided 2,400 by ten to find out how many bundles you needed.
Thank you,

The first thing i did was draw out a rectangle and put the dimensions. Then i figured out how many inches were in 10 and 15 feet .The length was 180 in. and i dived it by the dimensions of one of the tiles and i got 60 tiles with length. I did the same thing with the width was 120and i got 40 tiles as its width.Then i multiplied length x width tiles and got 2,400 tiles that she needs.
Then i took 2,400 and dived It by the number of tiles in a bundle {10} and i got 240 . So she needed 240 bundles of tiles.
The i took the 240 bundles of tiles and multiplied it by 3.50[the cost of each bundle] and i got that she would spend $840 on the new floor.
