<h3>Answer: C) 75</h3>
==============================================================
Explanation:
4:00 p.m. corresponds to x = 16, since 12+4 = 16
You can think of 4:00 p.m. representing 1600 hours in terms of military time.
Locate 16 on the x axis. Draw a vertical line until this vertical line crosses the blue parabola. Check out the diagram below.
From this point of intersection, draw a horizontal line until you move to the y axis. You should be somewhere between y = 60 and y = 90.
A good guess could be 75 since it is the midpoint of 60 and 90. Algebraically we confirm it as such: (60+90)/2 = 150/2 = 75
To be fair, we may not hit the exact middle and may be at y = 70 instead of y = 75. But I think the midpoint is a good estimate considering we don't have all the information.
Luckily 75 is on the list of choices, and the other choices aren't even close. So choice C is likely the answer.
