The revenue from selling x hats is r(x)=18x the cost of buying x hats is c(x)=8x+30. the profit from selling x hats is p(x)=r(x)-c(x)
write a function for p(x), the profit from selling x hats

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)

The revenue is: r(x)=18xThe 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

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
