A local water park found that if the price of admission was $19, the attendance was about 1550 customers per week. When the price of admission was dropped to $16,attendance increased to about 2350 per week. Write a linear equation for the attendance in terms of the price,p. (A = mp + b)

Answers

Answer 1

Given:

When the price of admission was $19, the attendance was about 1550 customers per week

And, when the price of admission was dropped to $16,

attendance increased to about 2350 per week

Let the attendance = A

And the price = p

The linear equation will be A = mp + b

Where (m) is the slope and (b) is the y-intercept

So,

When p = 19, A = 1550

When p = 16, A = 2350

So,

[tex]m=\frac{2350-1550}{16-19}=\frac{800}{-3}=-\frac{800}{3}[/tex]

So,

[tex]A=-\frac{800}{3}p+b[/tex]

we will find the value of (b) as follows:

[tex]\begin{gathered} 1550=-\frac{800}{3}\cdot19+b \\ 1550=-\frac{15200}{3}+b \\ b=\frac{19850}{3} \end{gathered}[/tex]

So, the answer will be the linear equation is:

[tex]A=\frac{-800}{3}p+\frac{19850}{3}[/tex]

Last year the book fair sold 200 bookmarks compared to the 180 sold this year. What is the percent of change in the number of bookmarks sold?

Answers

Answer:

Step-by-step explanation:

1. Subtract 200 from 180

200 - 180 = 20

2. Divide the difference of the number of bookmarks by last years

20 / 200 = 0.1

3. Multiply 0.1 by 100 to get the percentage

0.1 x 100 = 10 %

4. Since this is a reduction in number of bookmarks sold, then it would be a -10% change in the number of bookmarks sold.

MARY BOUGHT A CAR FOR $12,785 IF MARY PAID $2,000 DOWN AND WILL PAY $273.53 FOR 48 MONTHS WHAT IS THE TOTAL FINANCE CHARGE?

Answers

First, we will find the amount of money she will pay in 48 months

Since she pays $273.53 for 48 months, then

[tex]273.53x48=13,129.44[/tex]

Since she paid a $2000 down payment

Then we will add 2000 to 13,129.44 to find the total amount she paid

[tex]T=13129.44+2000=15,129.44[/tex]

Now, we will subtract the price of the car from it to find the finance charge

Since the price of the care is $12,785, then

Find the domain and range and intercepts.g of x = 3 / x-4

Answers

a) Domain; all real numbers except 4

b) Range; all real numbers except y = 0

c) Y-intercept = -0.75

d) x-intercept does not exist

Here, we want to find the domain, range and intercepts

The domain refers to the possible x-values

From the question, the function will hold for all values of x, except x = 4, where we will have an undefined expression

Thus, the domain is all real numbers, except x= 4

For the range, we are referring to the possible y-values

From the given equation the possible y values are all real numbers except y = 0

To find the intercepts, let us write g(x) as y

The equation is thus;

[tex]\begin{gathered} y\text{ = }\frac{3}{x-4} \\ \end{gathered}[/tex]

To get x-intercept, substitute y = 0

By doing this, we have no x-intercept

To get the y-intercept, we simply substitute x = 0

That means;

[tex]\begin{gathered} y\text{ = }\frac{3}{0-4} \\ y\text{ = }\frac{3}{-4} \\ y\text{ = -0.75} \end{gathered}[/tex]

A sinking fund is established to discharge a debt of $70,000 in 10 years. if deposits are made at the end of each 6-month period and interest is paid at the rate of 9%, compounded semiannually, what is the amount of each deposit? (round your answer to the nearest cent.)

Answers

The amount of each deposit is $210000

What is compound interest?

Compound interest is when you reinvest your income. Compound interest distinctively means "interest on interest" and is the reason so many investors are so successful.

The computation of the each deposit is shown below:

Given that

Future value be $70,000

Time period = 10 × 2 = 20

And, the rate = 9% ÷ 2 = 4.5%

Now the formula is as follows

= (Future value × rate of interest) ÷ (1 + rate of interest)^time period - 1

= ($70,000 × 4.5) ÷ (1 + 0.025)²⁰⁻¹

= $315,000 ÷ 1.5

= $210000

Answers

Answer:

The length of the playground = 11 yards

The width of the playground = 14 yards

Explanation:

Let the length of the playground = l yd.

The width of the playground is 3 yd longer than its length.

Therefore, the width of the playground = (l+3) yd

Area of a Rectangle = Length x Width

Substituting the given values, we have:

Annie purchased a season pass for the new aquarium at a cost of $110.

If she uses the pass 10 times this year then we have to find the unit rate in cost per visit.

We have to find the unit rate.

Unit rate means finding the value of one object, that means we have to find the cost of one visit.

The cost of season pass is $110.

She visit aquarium 10 times.

We find the unit rate cost per visit by dividing the total cost of season pass  for the new aquarium by total times she visits in the new aquarium.

10 times = $110 cost

Divide by 10 on both side

10/10 times = $110/10 cost

1 times = $11 cost

What is the equation for the line in slope-intercept form?

Answers

Answer:

y = -2x - 4

Step-by-step explanation:

Slope intercept form : y = mx + b

Where

m = slopeb = y intercept

Finding Y - Intercept

The y intercept is the point where the line crosses the y axis.

Here, just by looking at the graph we can say that the y intercept is at (0,-4) because that is where the line passes the y intercept.

This means that b = - 4

Finding the slope

We can find the slope using the following formula

Slope = (y2-y1)/(x2-x1)

Where, (x1,y1) and (x2,y2) are any given points on the line

The points used can vary however I have chosen (0,-4) and (-2,0)

Defining our variables we get (x1,y1) = (0,-4) and (x2,y2) = (-2,0)

So we have x1 = 0 , x2 = -2 , y1 = -4 and y2 = 0

We now plug this in to the formula

Slope = (y2-y1)/(x2-x1)

==> plug in x1 = 0 , x2 = -2 , y1 = -4 and y2 = 0

Slope = (0-(-4))/(-2-0)

==> remove parenthesis

Slope = (0+4)/(-2-0)

==> simplify addition and subtraction

Slope = 4/-2

==> simplify fraction

Slope = -2

So the slope or "m" is -2

Plugging the y intercept and slope into y intercept form

Again we have y = mx + b

m = slope so m = -2 and b = y intercept so b = -4

Plugging this in, we acquire y = -2x - 4
