HELP ASAP A furniture manufacturer must pay $16.91 to make a certain kind of chair, which it can sell for $55.75. If the manufacturer has starting overhead costs of $18,340, not including production costs, how many chairs must it sell to realize a profit of $24,850, to the nearest chair?
a. 1,112
b. 918
c. 775
d. 640
(10 points and brainliest if the answer is right)
Answer:
A. 1,112
Step-by-step explanation:
The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.
Option A is the correct answer.
What is an expression?
An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example: so
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Let's start by finding the profit per chair:
So,
Profit per chair = Selling price - Production cost
= $55.75 - $16.91
= $38.84
Next, we need to determine how many chairs the manufacturer needs to sell to make a profit of $24,850:
Profit = Profit per chair x Number of chairs sold - Overhead costs
$24,850 = $38.84x - $18,340
$43,190 = $38.84x
x = 1,112.49
Rounding to the nearest whole number, the manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.
Therefore,
The manufacturer needs to sell approximately 1,112 chairs to realize a profit of $24,850.

Find an equation for the line below. Thanks !
Answer:
[tex]\huge\boxed{y=\frac{1}{4}x + \frac{13}{4}}[/tex]
Step-by-step explanation:
In order to find the equation to this line, we need to note that we see two points on this graph. Using these two points, we can use them to find the slope of the graph and use one to find the y-intercept.
We know that the slope of a line is defined by [tex]\frac{\Delta y}{\Delta x}[/tex] (change in y / change in x). Therefore, we can use our two points that we know - (-5, 2) and (3, 4) to find the slope.
The change in y is [tex]4 - 2 = 2[/tex], and the change in x is [tex]3 - (-5) = 3+5= 8[/tex]. Therefore, our slope is [tex]\frac{2}{8} = \frac{1}{4}[/tex].
Now that we know our slope, our equation in slope-intercept form looks something like this.
[tex]y = \frac{1}{4}x + b[/tex]
However, we still have b to solve for. We can solve for this by substituting a point we already know into the equation. Let's substitute (3, 4) inside.
[tex]4 = \frac{1}{4} \cdot 3+b[/tex] [tex]4 = \frac{3}{4} + b[/tex] [tex]b = \frac{16}{4}- \frac{3}{4}[/tex] [tex]b = \frac{13}{4}[/tex]So now we know that the y-intercept is [tex]\frac{13}{4}[/tex]. Plugging that into our equation finishes it off, leaving our final equation to be [tex]y = \frac{1}{4}x + \frac{13}{4}[/tex].

Find X- and y- intercepts of the graph of each equation.
Answer:
1.) -4 and 12
y-intercept: -4
x-intercept: 12
2.) -11 and 11
y-intercept: -11
x-intercept: 11
Step-by-step explanation:
x - 3y = 12
0 - 3y = 12
-3y/-3 = 12/-3
y = -4 (y-intercept)
x - 3y = 12
x -3(0) = 12
x = 12 (x-intercept)
2x - 2y = 22
2(0) - 2y = 22
-2y = 22
-2y/-2 = 22/-2
y = -11 (y-intercept)
2x - 2y = 22
2x - 2(0) = 22
2x = 22
2x/2 = 22/2
x = 11 (x-intercept)

x = 9
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
50° is an exterior angle of the triangle, thus
38 + 4x - 24 = 50 , that is
14 + 4x = 50 ( subtract 14 from both sides )
4x = 36 ( divide both sides by 4 )
x = 9
Answer:
[tex]\huge\boxed{\sf x = 9}[/tex]
Step-by-step explanation:
The measure of the exterior angle is equal to the sum of non-adjacent interior angles.
So,
50 = 38 + 4x - 24
50 = 4x + 14
Subtract 14 to both sides
50 - 14 = 4x
36 = 4x
Divide 4 to both sides
36 / 4 = x
x = 9

When subtracting with negative numbers, change the problem to an
problem and
Answer:
Subtracting a number is the same as adding the opposite of the number
Step-by-step explanation:
Subtracting a negative number from a negative number – a minus sign followed by a negative sign, turns the two signs into a plus sign. So, instead of subtracting a negative, you are adding a positive. Basically, - (-4) becomes +4, and then you add the numbers. For example, say we have the problem -2 - –4.

the sum of two number is 45. if one of them is 27 find other in equation with process
Step-by-step explanation:
Hey there!
Given;
The sum of two numbers is 45.
One of them is 27.
Let next number is "x".
So, Add "x" and "27" and show it is equal to 45.
Or, x+27 = 45
Therefore, x+27 = 45 is the required equation.
Now, solving unknown number.
~ Take "27" to right side and subtract it.
x= 45 - 27
X= 18
Therefore, next number is (x) = 18.
Hope it helps...

Adult tickets were $5 each and student tickets were $3 each. The members of the band sold a total of 4,000 tickets. How many student tickets did they sell
Answer:
Adults =1500 and student= 2500
Step-by-step explanation:
Step one:
GIven data
let Adults be x and student be y in numbers
so
5x+3y=15000------------1
x+y=4000---------------------2
from 1
x=4000-y, put this in 2, we have
5(4000-y)+3y=15000
20000-5y+3y=15000
-2y=15000-20000
-2y= -5000
2y=5000
divide both sides by 2
y= 2500
put y= 2500 in 2
x+2500= 4000
x= 4000-2500
x=1500
A taxi service charges a base fee of $5.00 for each fare. In addition, the service charges a $1.75 per minute fee. Which equation relates the total cost of a fare, , to the length of the ride, in minutes, ?
Answer:
Equation is = 5+1.75m
Step-by-step explanation:
Given that,
A taxi service charge is $5.00 for each fare.
In addition, the service charges a $1.75 per minute fee.
It means, for every minute, $1.75 increases with time and $5.00 is fixed.
ATQ,
Total cost = 5+1.75m
Where m is time in minutes
Hence, the required equation is "5+1.75m".
Find the slope:
(3,-5) and (-7,-6)
the slope is 0.1 or one tenth as a fraction.
slope equation:
change in Y divided by change in X
**underlined numbers are x values and bold numbers are y values**
(3,-5) and (-7, -6)
our two Y values looking at the coordinates are -5 and -6, since coordinates are (x,y)
our two X values are 3 and -7
now plug these into the equation:
-5 - (-6)
------------
3 - (-7)
**PAY ATTENTION TO THE SIGNS**
now the numerator is -5+6 which is 1
and the denominator is 3+7 which is 10
that makes 1/10 as a fraction -your slope
simplify it and you have:
slope = 0.1 or 1/10

x .... y0 .... 22 .... 64 .... 106 .... 14Rate of change for the given line is:
(6 - 2)/2 = 4/2 = 2y- intercept is 2Equation for the line is:
y = 2x + 2For the point (40, 76) we can verify with the equation:
40*2 + 2 = 82The point (40, 76) is close the line but the line doesn't pass through it.
Answer:
x | y
0 | 2
2 | 6
4 | 10
6 | 14
Equation of the line is
[tex] \frac{y - 2}{x - 0} = \frac{6 - 2}{2 - 0} \\ \frac{y - 2}{x} = \frac{4}{2} = 2 \\ y - 2 = 2x \\ y - 2x = 2\\ \boxed{y=2x+2}[/tex]
When x=40, y will be (2×40)+2 =82
So the point should pass through (40,82) and not (40,76).

what is the slope (2,-9) (-2,9)
Answer:

Step-by-step explanation:
[tex]\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}[/tex]
(2, -9) ⇒ x₁ = 2, y₁ = -9
(-2, 9) ⇒ x₂ = -2, y₂ = 9
