Answer:
C. 39
Step-by-step explanation:
m∠3 ≅ m∠5
4x - 7 = 6x - 81
-7 = 2x - 81
74 = 2x
37 = x
m∠5 = 6(37) - 81 = 141
m∠8 = 180 - 141 = 39
The answer would be 6/15+10/15. You get this by finding the common denominator which is 15 by multiplying 3 and 5 by 3 and 2 and 3 by 5

Step-by-step explanation:
Please correct me if I'm wrong. :)
So here, we are starting with two numbers: the original price, and the price after the percent increase.
First, we need to find the differences between the prices to figure out how much of a difference the percent made. $181.09 - $102.30 = $78.79
$78.79 is how much money the original price was increased by. We can find the percent change using this, since this number is what percent of the original price went up.
So now: $78.78 / $102.30 = .77018
And now, we convert that to percent: 77%
The markup was 77%.
4$-20%
X$-100%
X=4·100:20=400:20=20
