given the weekly demand curve of a local wine producer is p= 50-0.1q, and that the total cost function is c= 1500+ 10q, where q

ipn [44]

Answer:

a)the weekly profit as a function of price is $P=-10 p^2 + 600 p - 6500$

b) a bottle of wine be sold at $30 to realise maximum profit

c) the maximum profit that can be made by the producer is $2500

Step-by-step explanation:

The weekly demand curve of a local wine producer is p= 50-0.1q

p = price

q = quantity

Revenue function R =Price \times Quantity

R=(50-0.1q)q

$R=50q-0.1q^2$

Cost function: c= 1500+ 10q

Profit function=R(x)-C(x)

Profit function= $50q-0.1q^2-1500-10q$

Profit function= $40q-0.1q^2-1500$ ----1

We have q = 500 - 10 p using p = 50 − 0.1q

$P=-0.1 (500 - 10 p)^2 + 40 (500 - 10 p)- 1500\\P= -10 p^2 + 600 p - 6500$

General quadratic equation: $ax^2+bx+c=0$

On comparing

a = -0.1 , b = 40 , c = -1500

Maximum Profit is at q = $\frac{-b}{2a}=\frac{-40}{2(-0.1)}=200$

To find price must a bottle of wine be sold to realise maximum profit

p= 50-0.1q

p= 50-0.1(200)=30

Substitute the value of q in profit function(1) get the maximum profit

So, Profit function= $40\left(200\right)-0.1\left(200\right)^{2}-1500=2500$

Hence

a)the weekly profit as a function of price is $P=-10 p^2 + 600 p - 6500$

b) a bottle of wine be sold at $30 to realise maximum profit

c) the maximum profit that can be made by the producer is $2500

Write the ratio 1.6 : 4 as a fraction in simplest form, with whole numbers in the numerator and denominator.

skad [1K]

1.6 : 4

1.6 is also equal to 8/5

therefore,

8/5 : 4

(8/5)/4

**get the reciprocal of the denominator (4) which is equal to 1/4**

(8/5)*(1/4)

(8/4)*(1/5)

2*(1/5)

2/5

two fifth is the answer

A certain stock starts the day at $273/8 per share. If it drops $21/2 during the day, what is its closing value? A. $247/8 B. $2

Elza [17]

Answer:

A. $ 24 7/8

Step-by-step explanation:

GIVEN: A stock starts the day at $27 3/8 per share.

Share drops $2 1/2 during the day.

To Find : Closing value

Solution : first we need to find how many 1/8 are there in 1/2

So, $\frac{\frac{1}{2} }{\frac{1}{8} } =4$

when share drops by $2 then share will be :

$27 - $2 =$25

and $\frac{3}{8} - 4(\frac{1}{8})$

⇒ $\frac{3}{8} - \frac{4}{8}$

⇒ $\frac{-1}{8}$

So, $25-\frac{1}{8}$

⇒ $24\frac{7}{8}$

So, its closing value is $24\frac{7}{8}$ .
