Johnny makes wooden benches to sell. His advertising costs are $150 per month and each bench costs him $100 to make. If he
sells each bench for $175, how many benches must he sell to break even each month?

2 benches

Step-by-step explanation:

1.)  150 + 100x = 175x

2.)  150 = 75x

Final 2  = x

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
