Answer: the first option is the correct answer.

Step-by-step explanation:

Let x represent the number of necklaces that he makes in a year.

Profit = Revenue - cost

The cost of making each necklace is $5. In making necklaces in a year, the fixed cost is $5000. This means that the total cost of making x necklaces in a year is

5x + 5000

Sam sells each necklace for $10 each. This means that the total amount made from selling x necklaces is $10x.

For Sam to make profit of $1000 in a year, the number of necklaces that she must sell would be

1000 = 10x - (5x + 5000)

1000 = 10x - 5x - 5000

10x - 5x = 1000 + 5000

5x = 6000

x = 6000/5

x = 1200

⇒ x =27(\frac{100}{45})

⇒ x =\frac{2700}{45}

⇒ x =60

Therefore , Brianna listen 60 songs on Saturday !
