A grocery store buys cereal using the cost function c(n) = { 2n when n < 100 1. 9n when 100 â‰¤ n â‰¤ 500 1. 8n when n > 500 where n is the number of boxes of cereal the grocery store buys and c(n) is the cost of the cereal. The grocery store then sells the cereal using the sales function s(c) = 1. 3c. What is the grocery store's sales from selling cereal if the grocery store buys 100 boxes and sells all of them?.

The** grocery store's sales** from **selling cereal** if the **grocery store** buys 100 boxes and sells all of them are **$247**

From the **given function**, we can see that the equivalent function for a number of **100 boxes** is given as;

c(n) = 1.9n

**If n = 100**

c(100) = 1.9(100)

c(100) = 190

Hence the cost of** 100 boxes** will be **$190 **

Given the** sales function** s(c) = 1. 3c, the grocery store's sales from **selling cereal** if the **grocery store** buys 100 boxes will be expressed as:

[tex]s(c) = 1. 3c\\s(190)=1.3(190)\\s(190)=$247[/tex]

what is the slope of the line with the equation: y+6=24-2x

**Answer:**

The slope is -2

**Step-by-step explanation:**

y+6=24-2x

Subtract 6 from each side

y+6-6=24-6-2x

y = 18 -2x

Rewriting

y = -2x+18

This is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

The slope is -2 and the y intercept is 18

Which is greater 25% of 16 or 20% of 25

**Answer:**

20% of 25 is greater

**Step-by-step explanation:**

25% of 16 = 4

20% of 25 = 5

**Answer:**

20% of 25

**Step-by-step explanation:**

To find 25% of 16, we have to consider how much 25% is out of 100%

25/100 can be simplified to 1/4

So 1/4 of 16 (or 16/4) = 4

To find 20% of 25, we have to consider how much 20% is out of 100%

20/100 can be simplified to 1/5

So 1/5 of 25 (or 25/5) = 5

4 < 5

Therefore, 20% of 25 is greater than 25% of 16

A small party balloon has a maximum volume of 500 cm3. Unfortunately, it has a leak that allows 10 cm of air to escape every second. a Write down an equation for the volume (v cm) of the party balloon, t secs after it starts to leak.

**Step-by-step explanation:**

I think you mean that 10 cm³ of air are escaping every second.

and we start with a volume of 500 cm³.

V = 500 - 10t 0 <= t <= 50

because negative t (seconds) don't make any sense, and neither does a negative volume (for t > 50).

How do you write an equation of a line so that it is parallel or perpendicular to a given point??

The equation of a line so that it is perpendicular to a given point will be

y-y0=[tex]\frac{-1}{m}[/tex] (x - xo)

The equation of a line so that it is perpendicular to a given point will be

y-y0=m (x - xo)

The standard equation of the line is better written in point-slope form expressed as:

y-y0=m(x - xo)

where: m is the slope of the given line (x0, y0) is any point of the giuven line.

m is the slope of the given line

(x0, y0) is any point on the given line

If the given slope of the line is m, the slope of the line perpendicular will be expressed as -1/m

The equation of a line so that it is perpendicular to a given point will be

y-y0=[tex]\frac{-1}{m}[/tex] (x - xo)

equation of the line (6,10) , (-3,-2)

The equation for this line is y=1.3x+2

**Answer:**

[tex]y=\frac{4}{3}x+2[/tex]

**Step-by-step explanation:**

using two points you can find the slope of the line using the formula [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

plugging in the x- and y- values into the equation above, you'll get:

[tex]m=\frac{-2-10}{-3-6}=\frac{-12}{-9}=\frac{4}{3}[/tex]

so far, you have [tex]y = \frac{4}{3}x+b[/tex]

using any of the two points, you can solve for b. in this case, the point (-3, -2) is used.

[tex]-2=\frac{4}{3}(-3)+b\\-2=-4+b\\-2+4=-4+b+4\\2=b[/tex]

the overall equation is [tex]y=\frac{4}{3}x+2[/tex]

The function g(x) = -3x - 6. Compare the slopes,

Help plz

**Answer:**

The slopes are equal

**Step-by-step explanation:**

Calculate the slope m of f(x) using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 1, 5) and (x₂, y₂ ) = (0, 2) ← 2 points on the line

m = [tex]\frac{2-5}{0-(-1)}[/tex] = [tex]\frac{-3}{0+1}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

g(x) = - 3x - 6 ← is in slope- intercept form

with slope m = - 3

Then the slopes of f(x) and g(x) are equal, meaning the lines are parallel

Your piggy bank contains quarters and dimes. There are 572 coins in the piggy bank totaling $92. How

many quarters and dimes are in the piggy bank

**Answer:**

**Step-by-step explanation:**

Let the number of dimes be x and quarters be y.

Dime = 10 cents, quarter = 25 cents, total amount is $92 = 9200 centsWe have equations:

x + y = 57210x + 25y = 9200Multiply the first equation by 10 and subtract from the second one:

10x + 25y - 10x - 10y = 9200 - 572015y = 3480y = 3480/15y = 232Find the value of x:

x + 232 = 572x = 572 - 232x = 340Simplify (x-4) (x^2 + 3x + 2)
