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)
p(x)=18x-(8x+30)
Solving=
p(x)=10x-30
<em>Be careful with the signs</em>
So the correct answer would be option :
c) p(x)=10x-30
