Yes it does I went on Desmos graphing Calculator and put in the equation and got those answers
First : -(-6) will turn into a positive 6
second: -8+6 which equals -2
To find how much the bike is reduced by, use multiplication.
Since you already know the bike is reduced by 30%, multiply that to the cost, $200.
200*30%=200*0.3=60
The bike is reduced by $60.
The bike now costs 200-60= $140
Hope this helps!
