3c-2(c+10)=7c-5(c+2)

Mathematics

Answer: C= -10

Step-by-step explanation: First step: simplify both sides of the equation

3c−2(c+10)=7c−5(c+2)

3c+(−2)(c)+(−2)(10)=7c+(−5)(c)+(−5)(2) (Distribute)

3c+−2c+−20=7c+−5c+−10

(3c+−2c)+(−20)=(7c+−5c)+(−10) (Combine Like Terms)

c + -20 = 2c - 10

c - 20 = 2c - 10

Step 2: Subtract 2c from both sides

c - 20 - 2c = 2c -10 - 2c

−c−20=−10

Step 3: Add 20 to both sides

−c−20+20=−10+20

−c=10

Step 4: Divide both sides by -1

-c/-1 = 10/-1

C=-10

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
