Mathematics
1 answer:
Alex787 [66]2 years ago
5 0

Answer:

-40%

Step-by-step explanation:

NV = new value

OV = old value

percent change = (NV - OV)/(OV) × 100%

percent change = (30 - 50)/(50) × 100%

percent change = -20/50 × 100%

percent change = -40%

The values of w is inversely proportional to m .if w=8 then m=25; what is m when w=20?
iren2701 [21]

Answer:

m = 10

Step-by-step explanation:

Given w is inversely proportional to m then the equation relating them is

w = \frac{k}{m} ← k is the constant of variation

To find k use the condition w = 8, m = 25 , then

8 = \frac{k}{25} ( multiply both sides by 25 )

200 = k

w = \frac{200}{m} ← equation of variation

When w = 20 , then

20 = \frac{200}{m} ( multiply both sides by m )

20m = 200 ( divide both sides by 20 )

m = 10

A company sells a chair for $450. It costs them $350 to make each chair, plus fixed costs for operation of $20,000
lianna [129]

The cost and revenue function of the company are as follows;

  • cost function = 350x + 20000
  • revenue function = 100x - 20000

<h3>How to find the cost and revenue function?</h3>

It costs them $350 to make each chair, plus fixed costs for operation of $20,000. Therefore,

let

x = number of chair

cost function = 350x + 20000

The company sells a chair for $450. Therefore,

revenue function = 450x  - (350x + 20000)

revenue function = 450x - 350x - 20000

revenue function = 100x - 20000
