Answer:

The correct answer is c) p(x)=10x-30

Step-by-step explanation:

The answer is given in the question, you just have to replace r(x) and c(x) in the profit formula.

p(x)=r(x)-c(x)

  1. The revenue is: r(x)=18x
  1. The cost is c(x)=8x+30

p(x)=18x-(8x+30)

Solving=

p(x)=10x-30

Be careful with the signs

So the correct answer would be option :

c) p(x)=10x-30
