svetoff [14.1K]

The profit equation which relates P, profit to N, quantity produced and sold is:

P=17.75N-750

What is the total cost function?

The total production cost function, whereby total cost is C is as given below:

C=750+15.95N(look at a similar question provided)

What is the total revenue function?

The total revenue function is as given below:

R=33.70N

The profit is the excess of total revenue over total cost, in other words, profit is the total revenue minus total cost

P=33.70N-(750+15.95N)

P=33.70N-750-15.95N

P=33.70N-15.95N-750

P=17.75N-750

Solve the following system.
Stolb23 [73]
From the second equation y=-1-x so we can write -2x²+3x-1=-1-x.
So -2x²+4x=0, 2x(-x+2)=0, therefore x=0 or 2 and the corresponding y values are -1 and -3.
We can write the answers as ordered pairs (0,-1) and (2,-3).

Artist 52 [7]

Answer:

$478.80

Step-by-step explanation:

We have been given that 15 players two coaches and 21 parents attend this year sports banquet the cost of each meal was $12 plus 5% sales tax.

First of all, we will find cost of each meal with tax as:

\text{Cost of each meal with tax}=\$12+\$12\times \frac{5}{100}

\text{Cost of each meal with tax}=\$12+\$12\times 0.05

\text{Cost of each meal with tax}=\$12+\$0.6

\text{Cost of each meal with tax}=\$12.6

Now, we will find total persons at the sport banquet as:

\text{Total persons at banquet}=15+2+21

\text{Total persons at banquet}=38

To find the total cost of food for the banquet, we will multiply cost of food for each person by 38.

\text{Total cost of food for the banquet}=\$12.6\times 38

\text{Total cost of food for the banquet}=\$478.8

Therefore, the total cost of food for the banquet is $478.80.

Given the system:
mina [271]

Answer:

X= -3

Y= 7

a= -6

b = -28

C = 9

D= -7

Step-by-step explanation:

2x – 4y = -34

-3x - y = 2

2x – 4y = -34

-12x - 4y = 8

-14x = 42

X= 42/-14

X= -3

-3x - y = 2

-3(-3) -y = 2

9-y = 2

9-2= y

Y= 7

a = 2x

a= 2*-3

a= -6

b = -4y

b = -4*7

b = -28

C= -3x

C= -3*-3

C = 9

D= -y

D= -7
