Question

Use the system of equations to find how many

necklaces Joan needs to sell to break even.
Enter the correct answer.
Joan is selling handmade bead necklaces
at a local art fair. She paid $170 to
reserve her booth. The cost of supplies
for each necklace averages $2. So, her
cost, y, for x necklaces is represented by
y = $170 + 2x. If she sells her necklaces
for $12, her revenue, y, is represented
by y = 12x

The solution of this system is the break-
even point, the point beyond which she
starts making a profit.​

Answer 1

Answer: 17

Explanation:

To break even your revenue must be equal to your cost.

So, 12x=170+2x

12x-2x=170

10x=170

x=170/10=17

So, Joan needs to sell 17 necklaces to break even.
