Finding the Break-Even Point and the Profit Function Using Substitution Given the cost function C(x)=0.85x+35,000 and the revenue function R(x)=1.55x,find the break-even point and the profit function?

Respuesta :

Answer:

[tex]x=50000[/tex]

[tex]P(x)=0.7x-35000[/tex]

Step-by-step explanation:

Given cost function is

[tex]C(x)=0.85x+35000[/tex]

and revenue function is

[tex]R(x)=1.55x[/tex]

At break even point, revenue is equal to cost

R(x)= C(x)

[tex]1.55x=0.85x+35000[/tex]

Subtract 0.85 from both sides

[tex]0.7x=35000[/tex]

divide by 0.7 on both sides

[tex]x=50000[/tex]

Profit function

P(x)= R(x)- C(x)

[tex]P(x)=1.55x-(0.85x+35000)[/tex]

[tex]P(x)=1.55x-0.85x-35000[/tex]

[tex]P(x)=0.7x-35000[/tex]
