notka56 [123]3 years ago
4 0

Answer:

  see below

Step-by-step explanation:

A graphing calculator does this very nicely.

___

If I were graphing by hand, I might divide by 4 and add 7 to get ...

  y = 3x +7

Now, you know the slope is 3 and the y-intercept is 7. Another point can be found by going left 1 and down 3 from the y-intercept, or left 2 and down 6 as shown on the attached graph. The line can be drawn through those points.

How many computers must the AB Computer Company sell to break even? Let x be the number of computers.
Eduardwww [97]

Answer:

The Company AB must sell 116 computers to break even

Step-by-step explanation:

we have

R(x)=1.5x -----> equation A

C(x)=145+\frac{1}{4}x ----> 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

Solve for x

subtract 1/4x both sides

1.5x-\frac{1}{4}x=145

1.5x-0.25x=145

1.25x=145

Divide by 1.25 both sides

x=116

therefore

The Company AB must sell 116 computers to break even

Vladimir [108]

Answer:

I think the closest would be 41.5%

Step-by-step explanation:

If you take the number of passengers left on the plane and divide by the total number of passengers that were on the plane in the beginning, you would get 58.5%. That's the % of how many people are left on the plane. So, you would then do 100%-58.5% to get the answer 41.5%. Hope this helps! :)
