First one is C second one is D. In the first one, the line is between 0 and 240 and in the second one brackets mean a closed point while parentheses mean an open point
For this case, what you should do is to see the behavior of the graph as you move away to minus infinity or to more infinity on the x axis.

x ---> - inf then,
y -----> - inf
Answer:
option 4
Price for company A:
p(A) = 10 + 5*h
Price for company B:
p(B) = 7*h
,where h is the hours.
To find the hours after which the prices for both are going to be the same, we set the price for A equal to the price of B and calculate h.
10 + 5*h = 7*h <=>
2*h = 10 <=>
h = 10/2 <=>
h = 5 hours
80%
I think
Because if each dime is 10% then I think that’s works
