Answer:
Option D. 1200
Step-by-step explanation:
The making cost of necklaces = $5.00 each
Selling price of necklaces = $10.00 each
Sam's fixed costs per year for her jewelry business = $5,000
Let x be the number of necklaces, she sells in order to make a profit of $1,000 in a year.
Cost price of x necklaces = 5x + 5000
Selling price of x necklaces = 10x
We know that Profit = selling price - cost price
Profit = 1000 = 10x - (5x + 5000)
1000 = 10x - 5x - 5000
1000 = 5x - 5000
5x = 1000 + 5000
5x = 6000
![x=\frac{6000}{5}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B6000%7D%7B5%7D)
x = 1200
Sam must sell 1200 necklaces in order to make a profit of $1000.
