The answer is “equation F can be written as 2d+1 =3D +7
Let's turn that into a linear system:
Set the equations equal to each other and solve:
We then plug in to get
:
The solution to the system is
.
Now, let's turn our attention to the statements.
The first one is
false: Emilia's rate is higher, and the two plans cost the same at 50 texts, after which point Hiroto's plan becomes
cheaper!
The second one is also
false: we already figured out that the lines intersect at
.
The third statement is also
false: as above, the lines intersect at
.
The fourth statement is
true: the lines intersect at
.
In conclusion, the fourth statement - "Both plans cost the same when 50 texts are sent" - is true.
I believe the answer to your question is 10/37.
The total of candies inside the bag was initially 38. Since a blue candy has already been picked and cannot be picked and cannot be replaced then the total number of candy remaining in the bag is 37. So the probability of choosing a red candy is now 10/37
