C. 50cm
Step-by-step explanation:
40 * 10 = 400miles
5 * 10 = 50cm
The expected value would be 12 as it has the highest P(outcome).
What you do is you rearrange and simplify both equations to have them in terms of y, and then graph them. If it asked for a solution, their point of intersection would be the solution.
The first answer is C.
The second answer is A.
