Answer:
1. no solutions
2. one solution
Step-by-step explanation:
1. -4(5-3x)=12x+20
-20+12x=12x+20
-40+12x=12x
-40=0?????
So no solutions.
2. 3x+7(x+1)=2(6x+5)+2
3x+7x+7=12x+10+2
10x+7=12x+12
-2x+7=12
-2x=5
x=-5/2
So one solution.

Answer:
Answer is $10,144.50
Step-by-step explanation:
15% of 220 =33
220- 33 = 187
8.5% of 187 =15.89
187+15.89=202.89
202.89 x 50 =10,144.50
It subtracts 2 then adds 5
If she got 5/100 wrong she got 95%
95% is the same as 0.95
