Answer:
40
Step-by-step explanation:
Let's use the Rule of Three Simple to answer the question this way:
Stock price Percentage
$ 15 100%
$ 9 x
15 * x = 9 * 100
15x = 900
x = 900/15
x = 60
Percentage decreased = 100 - 60
Percentage decreased = 40
The company's stock decreased 40 percent
The decrease in the stock price from $15 to $9 represents a 40% decrease. We arrived at this result by subtracting the lower price from the higher one, dividing the result by the original price and then multiplying by 100.
The question asks about how much the stock price of a company decreased from $15 per share to $9 per share. In this case, the first step is to determine the difference in the stock prices, which is $15 - $9 = $6. To find the percentage decrease, we divide this difference by the original price and multiply by 100:
($6 / $15) * 100 = 40
Therefore, the stock price decreased by 40%. It's important to understand that stock prices can fluctuate based on a variety of factors, as seen in stock market histories such as the case of Netflix, whose stock price has experienced significant changes over the years. Nevertheless, the principle of calculating the percentage decrease remains the same.

Stops Price (dollars)
3 6.50
7 12.50
11 18.50
What is the initial fee?
Answer:
Initial Fee is $2.
Step-by-step explanation:
Given:
Stops Price (dollars)
3 6.50
7 12.50
11 18.50
Also Given:
The price of a train ticket consists of an initial fee plus a constant fee per stop.
So let the Cost of initial fee be 'x'.
Also Let the Cost of Constant fee be 'y'.
Now Equation can framed as;
Now According to table;
Number of stops = 3
Price = 6.50
So equation can be framed as;
Also According to table;
Number of stops = 7
Price = 12.50
So equation can be framed as;
Now Subtracting equation 1 from equation 2 we get;
Substituting the value of y in equation 1 we get;
Hence Initial Fee is $2.
The initial fee of a train ticket, given a constant fee per stop, can be calculated by finding the constant fee per stop and subtracting the total of this fee for a given number of stops from the total price for those stops. By this calculation, the initial fee is $2.50.
To determine the initial fee that is related to the price of a train ticket, which consists of an initial fee plus a constant fee per stop, we should first calculate the cost per stop. We can do this by subtracting the price of a ticket for 3 stops from the price of a ticket for 7 stops. So, we get $12.50 - $6.50 = $6.00. We find the difference in the number of stops, which is 7 - 3 = 4 stops. Divide the total price difference by the difference in the number of stops to get the constant fee per each stop: $6.00 / 4 stops = $1.50 per stop. Now we know the constant fee for each stop, so we subtract that from the total price for 3 stops to find the initial fee: $6.50 - ($1.50 * 3) = $2.50. So, the initial fee is $2.50.
To find the initial fee, we need to determine the additional cost per stop. We can do this by using the formula y = mx + b, where y represents the price of the ticket, x represents the number of stops, m represents the constant fee per stop, and b represents the initial fee.
Using the given data, we can set up two equations using the points (3, 6.50) and (7, 12.50).
By subtracting these two equations, we can determine the value of b, which represents the initial fee. Thus, the initial fee is $3.

look at image below
In October, they charged $1.50 for each flower. The October price was a 20% increase of the September price.
Part A:
What was the price of the flowers in September?
Part B:
The seventh-grade class earned 40% of the selling price of each flower.
In September, they sold 900 flowers.
In October, they sold 700 flowers.
Did they earn more money in September or October?
How much more?
Answer:
$1.25
September
$30
Step-by-step explanation:
Let's take this a step a time.
First we need to find how much the price of the flowers were in September.
We know that each flower cost $1.50 on October.
The October price was a 20% increase of the September price.
To calculate for the price of the flowers on September, we can solve it like this:
Let x = Price during September
1.2x = 1.50
We used 1.2 because the price of $1.50 is 120% of the original price.
Now we divide both sides by 1.2 to find x.
x = 1.25
The price of the flowers during September was $1.25 each.
Now the 7th grade class earned 40% of the selling price of each flower.
40% = 0.40
To find how much they made on each month, we simply multiply the percentage to the price and the number of flowers sold.
September = 0.40 x 1.25 x 900
September = 0.5 x 900
September = $450
Now for October.
October = 0.40 x 1.50 x 700
October = 0.6 x 700
October = $420
The 7th Graders earned more on September.
They earned $30 more on September than October.
