Answer:
The answer is "H [93%, 100%]"
Step-by-step explanation:
<em>I'll edit this in a second to show the process, but it may take a minute. Just have the answer for now.</em>
<em>This is a surprisingly useful question hah, I'll bet many will need to do this.</em>
This question is just finding the average. Pretty simple.
y = 86 + 82 + 91 + 98 + x / 5
y = 357 + x / 5
An easy way is to do the lowest question first, then go from lowest to second lowest and so on. Because if you go to the highest one and the answer is one of the lower ones, well, of course it's going to be within the 90-100 range, but that doesn't necessarily mean it's the answer.
y = 357 + (87) / 5
y = 444 / 5
y = 88.8
Okay, so the answer isn't G. Then let's try H.
y = 357 + (93) / 5
y = 450 / 5
y = 90
Yep, the answer is H. This is because it equals 90, which is indicative of the 90-100% range that Latoya needs to get an "A".
Final Price: $81
Process: 90 x 1.80 = 162
162 x 0.5 = $81

Answer: 10 feet</h3>
===================================================
How to get this answer:
A pentagon has 5 sides. If each side is the same length, then each side is 20/5 = 4 feet long. That halves to 4/2 = 2 feet. Each side is now 2 feet long, and there are 5 total sides, so 2*5 = 10 feet is the new perimeter.
A shortcut is to simply divide the perimeter in half to get 20/2 = 10. The reason why this works is because the perimeter is the sum of all the sides, which are all being cut in half.
-----
Algebraically, if we had the five sides a,b,c,d,e then
P = a+b+c+d+e
is the perimeter
Cutting each side in half gives
0.5*a+0.5*b+0.5*c+0.5*d+0.5*e = 0.5*(a+b+c+d+e) = 0.5*P
showing that we've cut the perimeter in half.
