Sam sells not necklaces for $10 each. each necklace cost her $5 to make. she also has $5,000 in fixed costs per year for her jewelry business. how many necklaces must she sell in order to make a profit of $1,000 in one year?

1200 necklaces.

Step-by-step explanation:

Profit = revenue - costs

We have:

1000 =  10x - 5x - 5000    where x is the number of necklaces she must sell.

1000 + 5000 = 5x

x = 6000/ 5

= 1200 (answer).
