1, A and D are the same thing But I would go with C. Hope this Helps!
The base is 7 units and the height is 3 units
On call = 3.5 hours for 10 dollars => ½ hour for 1.25 dollars. Now, let’s solve the unit rate for each company first = 3.5 hour / 10 dollars => 10 / 3.5 => Unit rate is 2.9 dollars/hr Second company = ½ hour for 1.25 dollars => 1.25 / .5 => 0.25 dollars / hr. Thus, the first company pays better than the second one because it pays 2.9 dollars every hour of talk compare to the 2nd one which pays only 0.25 dollars per hr.
Hope that helps =3
The answer would be A the other lines make no sense when you’re placing something on graph the line is always straight
Im not entirely sure, but im pretty sure its 2,546, hope this helps
