$8 * 25 hrs = $200 a week w/out taxes taken

Answer: B. 40</h3>
For any triangle, the three angles always add to 180
(y+10)+(2y)+(50) = 180
3y+60 = 180 ... combine like terms
3y+60-60 = 180-60 ... subtract 60 from both sides
3y = 120
3y/3 = 120/3 .... divide both sides by 3
y = 40
$14.8 was the markup, And the price went up in 22%, how I got my answer!
I first found that adding $64+$14.8=$78.8, and for percentage, that took awhile. At first I thought that it would be 20% but upon further investigation I found that, 22% Of $64 is $14.8.
I hope this helps!
P.S. 20% of $64 is $12.8.
