Complete Question

Kerrie is tiling the floor of a kitchen. The kitchen floor measures 11.3 feet by 9.25 feet. She orders enough tiles for 99 square feet. Which statement about the amount of tiles is correct?

a) Kerrie estimated correctly by rounding down. She has enough tile. The exact area is 104.5 square feet.

b) Kerrie estimated correctly by rounding up. She has enough tile. The exact area is 104.5 square feet.

c) Kerrie did not estimate correctly by rounding up. She does not have enough tile. The exact area is 104.5 square feet.

d) Kerrie did not estimate correctly by rounding down. She does not have enough tile. The exact area is 104.5 square feet.

Answer:

a) Kerrie estimated correctly by rounding down. She has enough tile. The exact area is 104.5 square feet.

Step-by-step explanation:

In mathematics we have what is defined as rounding up and rounding down.

Rounding up of numbers is when the number you want to round up is followed by number from 5 to 9(5, 6, 7, 8, 9)

E.g. 2.5 rounded up to the nearest whole number = 3

Rounding down of numbers is when the number you want to round up is followed by number from 1 to 4(1, 2, 3, 4)

E.g. 2.4 rounded down = 2

We are told in the question

Kerrie is tiling the floor of a kitchen. The kitchen floor measures 11.3 feet by 9.25 feet. She orders enough tiles for 99 square feet.

Kitchen floor is rectangular = Area = Length × Width

= 11.3 × 9.25 feet

= 104.525 square feet

We are told that Kerrie ordered for 99 square tiles.

But looking at the decimal, the number after the decimal are between 1 and 4.

Hence, she would be rounding down.

If Kerrie rounds down to the nearest whole number

11.3 feet = 11 feet

9.25 feet = 9 feet

Finding the area = 11 feet × 9 feet

= 99 square feet

Therefore, the correct statement = option a) Kerrie estimated correctly by rounding down. She has enough tile. The exact area is 104.5 square feet.

lianna [129]
S+m+l=28
4s+2m+l=58
6s+5m+4l=135

Eliminate the variable l from the first 2 equations

s+m+l=28
-4s-2m-l=-58
-3s-m=-30

Elminiate the variable l from the last 2 equations

6s+5m+4l=135
-16s-8m-4l=-232
-10s-3m=-97

Now solve for s and m using the 2 equations without l

-3s-m=-30
-10s-3m=-97

9s+3m=90
-10s-3m=-97
-s=-7
s=7

Then plug in s into one of the equations without l

-3(7)-m=-30
-21-m=-30
-m=-9
m=9

Now plus in s and m into one of the original 3 equations

(7)+(9)+l=28
16+l=28
l=12

Final answer:
Small=$7
Medium=$9
Large=$12

I know it only asks for large but I wanted to show you how to find them all for future reference. :)
