Answer:
The Company AB must sell 116 computers to break even
Step-by-step explanation:
we have
-----> equation A
----> equation B
where
C is the cost function
R is the revenue function
x is the number of computers sold
we know that
Break even is when the cost is equal to the revenue
so
equate equation A and equation B
![1.5x=145+\frac{1}{4}x](https://tex.z-dn.net/?f=1.5x%3D145%2B%5Cfrac%7B1%7D%7B4%7Dx)
Solve for x
subtract 1/4x both sides
![1.5x-\frac{1}{4}x=145](https://tex.z-dn.net/?f=1.5x-%5Cfrac%7B1%7D%7B4%7Dx%3D145)
![1.5x-0.25x=145](https://tex.z-dn.net/?f=1.5x-0.25x%3D145)
![1.25x=145](https://tex.z-dn.net/?f=1.25x%3D145)
Divide by 1.25 both sides
![x=116](https://tex.z-dn.net/?f=x%3D116)
therefore
The Company AB must sell 116 computers to break even
Answer: the answer is C
Step-by-step explanation:
For #32,
P=2L+2W
Subtract 2W from both sides, and swap left and right
2L = P-2W
Divide by 2
2L/2=(P-2W)/2
L = P/2 - 2W/2
L=P/2 - W
For #35
Most of the expenses are in fractions (of the original amount, A), so they can be added:
A/4 + A/5 + 2A/5 + 750 = A
add the fractions, with a common denominator of 20,
5A/20 + 4A/20 + 8A/20 +750 = A
(5A+4A+8A)/20 +750 = A
17A/20 + 750 = A
Now subtract 17A/20 from both sides and swap left and right
A - 17A/20 = 750
(3/20)A = 750
Multiply both sides by 20/3 (to make one unit of A on the left)
(3/20)*(20/3) A = 750*20/3
A =250*20=5000
Answer:
Independent Variable: Number of hours
Dependent Variable: Cost
Equation: C = 2x + 6
Step-by-step explanation:
The independent variable (x) is the variable that is manipulated. In this instance, that would be the number of hours a person rents out the bike.
The dependent variable (C) is the variable that is manipulated depending on the value of the independent variable. In this instance, that would be the total cost for renting the bike.
The total equation would be C = 2x + 6. The coefficient, 2, represents the charge of $2 per hour and the 6 represents the starting charge of $6.
