Answer:
The couch should be priced at 163.85
Step-by-step explanation:
multiply the wholesale price by %145
3x-4y-8=12
first combine like terms
3x-4y=12+8
then isolate on variable
3x=20+4y
now divide by three to find x
x=20/3+4/3 x=8
to find y plug in x to the original equation
3(8)-4y-8=12
24-4y=20
-4y=20-24
-4y=-4
y=1
