Step-by-step explanation:
hope this helped!
The answer should be
780x + 1500y=31000
please correct me if i'm wrong
25% is being taken off the original price, p, of each patio chairs.
That means the price of each patio chair is the full price, p, minus <span>25% of the original price.
1) To find 25% of the original price, multiply p (original price) by the decimal form of 25%, or 0.25. That means 25% off original price = 0.25p.
2) Now subtract 0.25p from the original price of the chairs to find the price of each (1) chair. p - 0.25p
Shylah is buying 4 chairs at that discounted price. That means you need to multiply the discounted price, </span> p - 0.25p, by 4. Shylah is paying 4(p-0.25p) total for the 4 chairs, which is answer choice B.
Since you can choose more than one choice, you can simplify 4(p-0.25p) by subtracting what is in the parathesis, then multiplying, following the order of operations:
4(p-0.25p)
= 4(0.75p)
= 3p
That is answer choice A.
--------
Answer: Choices A and B, <span>3p and 4(p−0.25p).</span>
Answer:


Step-by-step explanation:
Given

Solving (a): The cost function:
From the given parameter, it shows that the number of floor has no effect on the floors.
So, represent the floors with x.
The cost function is:

Solving (b): The slope and its interpretation
A function is represented as:

Where:

By comparing:
to 

So:

<em>What it means is that, no matter the number of floors, the cost remains unchanged.</em>
The greatest common factor of these three numbers is 4.
In order to find this, we start with factors of the smallest number (12). The factors are listed below.
12, 6, 4, 3, 2, 1
Now we start with the biggest and work our way down until we find something that goes into all 3.
12 does not go in evenly to either 44 or 28, so we can't use that.
6 does not go in evenly to either 44 or 28, so we can't use that.
4 goes in evenly to both as seen below:
44/4 = 11
28/4 = 7
Therefore, 4 is the greatest common factor.
