maria [59]

Answer:

4,280\ passes

Step-by-step explanation:

Let

x -----> the number of annual visitors pass sold

we know that

To find out the number of annual visitor passes sold, divide the total amount raised by the cost of a pass.

so

The linear equation that represent this problem is

12.50x=53,500

Solve for x

Divide by 12.50 both sides

x=\frac{53,500}{12.50}=4,280\ passes

Which of the following equations is equivalent to
andrew-mc [135]

Answer:

B. y=3x+12

Step-by-step explanation:

Hi there!

We want to find out which equation is equivalent to -6x+2y=24

The equation is currently written in standard form, which is ax+by=c, where a, b, and c are integer coefficients, but a and b CANNOT equal zero

We can change the equation into slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept, as all of the answer options are in slope-intercept form.

To do that, we'll need to isolate y by itself on one side

So let's add 6x to both sides to remove it from the left side

-6x+2y=24

+6x        +6x

__________________

     2y=6x+24

Now divide both sides by 2 to get the value of y by itself (1y)

y=3x+12

The answer is B. y=3x+12

Hope this helps!

Norman purchased $420 of stock in Carnival Cruise Lines last week. That stock is now worth $525. Use your knowledge of percent c
zysi [14]

Answer:

The stock Norman purchased increased in its value by 25%.

Step-by-step explanation:

Original Value of the stock = $ 420

New(Current) value of the stock = $ 525

We have to find the percentage change in the value of stock. The formula to calculate the percentage change is:

\text{Percentage Change}=\frac{\text{New Value - Original Value}}{\text{Original Value}} \times 100\%

Substituting the given values into this formula results in:

\text{Percentage Change}=\frac{525-420}{420} \times 100\% \\\\ \text{Percentage Change}=\frac{105}{420} \times 100\%\\\\ \text{Percentage Change}=0.25 \times 100\% \\\\ \text{Percentage Change}=25 \%

A positive value of Percentage Change indicates a growth. This means that the stock Norman purchased increased in its value by 25%.
