Answer: 25%
Step-by-step explanation:
To find percent decrease, you take your final number minus your initial number, over your initial number, so you start with 6-8/8, and get 2/8 or 1/4, then you multiply that by 100, so you get 25. That's your percent decrease.
X and y would be the same
$8.28 eight dollars and 28 cents
8-3x=5*2
8-3x=10
-3x=10-8
-3x=2
x=-2/3
