Mathematics
Joan is selling handmade bead necklaces at a local art fair. she paid $250 to reserve her booth. the cost of supplies for each necklace averages $2. so, her cost, y, for x necklaces is represented by y=$250+2x. if she sells her necklaces for $12, her revenue, y, is represented by y=12x. use the system of equations to find how many necklaces joan needs to sell to break even.

Ответ:
y=12x is the amount she makes
If the amount she spent = the amount she makes then she break even
250+2x=12x
250=12x-2x
250=10x
So x = 250/10=25 necklaces she needs to sell to break even
Answer is 25 necklaces
