In the default window of a graphing calculator, there is only one intersection that you see.
However, if you zoom out, you will see that they are 3 intersections to the pair of equations.
Answer:
That's basically how you solve it
In 12 turns, she lands in a blue space 3 times.
12/3 =4
In 100 turns, it is expected that Myra would land on a blue space '100/4' times
100/4= 25
Which sums up to 25 turns
The answer is 300 divided by 20 which you would get 15.
