Answer:
option B
$28.80
Step-by-step explanation:
Given the question,
side length of one square tile = 9 inches
area of square tile = l² = 9² = 81 inches²
<h3>Step1</h3>
There are 48(96) = 4608 carpet tiles, so the company was making 4608($.05) = $230.40.
<h3>Step2 </h3>
Now, the company countered with square feet. We have a total of 4608(81) = 373,248 square inches.
1 square foot = 144 square inches.
373,248/144 = 2592 square ft.
2592($.10) = $259.20
$259.20 - $230.40 = $28.80
You can make some algebraic equations and solve it.
The first would be:

The second would be

You can then rearrange the second into

And subsitute it into the first like so:

After that, distribute the y into the parantheses.

Subtract the 21 on both sides and multiply by -1 on both sides:

You then can factor it into:

With Zero Product Property, we can determine y to be either -3 and 7. Since the variables are interchangable, you can say the same about x, just that whatever x is, y must be the other value.
Thus, the answer is 7 and -3.
I think this is the answer :)
Answer:
$38
Step-by-step explanation:
cost of ticket for adult = $22
cost of ticket for youngster = $16
______________________________
cost of ticket for John's mom = $22 as she is adult
cost of ticket for john = $16 as he is young , his age is less than 18 years
Total cost of ticket for John and his mother = $22 + $16 = $38
If you were to plan a party, you could use a linear equation. for example, the room you are renting is $500. The price for food per person is $10
