A company can sell 2000 magazine subscriptions at $40 each. For each $5 increase in the price, it will sell 200 fewer subscripti

AVprozaik [17]

Let x denote the number of times at which price is increased by $5 for each magazine.
{Write an expression for the total revenue of company}
Let y denote the total revenue of the company,
y = (2000 - 200x) × ($40 + $5x)
{200x is the number of subscriptions being lost due to the price increases}
{$5x is the amount of increase in price of each magazine}

y = 2000($40) + 2000($5x) - 200x($40) - 200x($5x)
y = $80,000 + $10,000x - $8000x - $1000x^2
y = $80,000 + $18'000x - $1000x^2
{Since the coefficient of x^2 is (-1000), this graph is a sad face curve. This means the only stationary point on the curve is a maximum point}
{Differentiate y in terms of x}
dy/dx = $18,000 - $2000x
{dy/dx = 0 at stationary point, or when gradient = 0}
dy/dx = 0
$18,000 - $2000x = 0
$2000x = $18,000
x = 9 {dollar signs cancel out when they are divided}

Subscription price to attain maximum revenue should be: $40 + (9 × $5) = $95

Hope this helps!

(picture) Factoring Polynomials: GCF PLEASEE HELP!!!!! a b c d

Jobisdone [24]

Answer:

Factored form is 4x(2x+3)

Step-by-step explanation:

$8x^2 + 12x$

The factors are

8x^2 ----> 2*2*2*x*x

12x -------> 2*2*3*x

GCF is 2 * 2 * x= 4x

Now we factor out GCF from 8x^2 + 12x

When we factor out GCF, divide each term by 4x

$4x(\frac{8x^2}{4x} +\frac{12x}{4x})$

4x(2x +3)

Factored form is 4x(2x+3)

Please Help Me On These Questions!!!!!! I need Help!!!!!

melisa1 [442]

1. This is one confusing question... But here is what I did
x = 2y + 1
y = $3y^{2}$ + 2x

So plug in Y to solve for X
x = 2 ( $3y^{2}$ + 2x) + 1
x = $-2y^{2}$ - $\frac{1}{3}$
Not sure if that's completely correct, but I'm positive I didn't make any mistakes...

5. You have to find the multiples of 60 so...

1 60
2 30
3 20
4 15
5 12 <---

7 = 12 - 5

-4(2x-3) + 4x = 9x -4x +8 -4 answer this

shtirl [24]

Answer:

x = 8/9

Step-by-step explanation:

-4(2x-3) + 4x = 9x -4x +8 -4

2x*(-4) -3*(-4) + 4x = 9x - 4x + 8 - 4

-8x + 12 + 4x = 9x - 4x + 8 - 4 {Combine like terms}

-4x + 12 = 5x + 4

12 = 5x + 4x + 4

12 = 9x + 4

12- 4 = 9x

9x = 8

x = 8/9
